A Journal, International Journal of Andrology called Inhibition of glucose catabolism in rat, hamster, rhesus monkey and human spermatozoa by α-chlorohydrin, Author is Ford, W. C. L.; Harrison, Anne; Takkar, G. L.; Waites, G. M. H., which mentions a compound: 60827-45-4, SMILESS is OC[C@H](O)CCl, Molecular C3H7ClO2, Safety of (2S)-(+)-3-Chloropropane-1,2-diol.

Spermatozoa from the cauda epididymis of rats treated with RS-α-chlorohydrin [96-24-2] (10 mg/kg/day for 7 days, orally) had the same ATP [56-65-5] content as control spermatozoa immediately after collection, but were unable to metabolize glucose [50-99-7] in vitro and so their ATP content declined more rapidly than that of control spermatozoa. The in vitro metabolism of glucose by spermatozoa from rat, hamster, rhesus monkey, and human was inhibited by ≥80% after 15-30 min preincubation in the presence of RS-α-chlorohydrin concentrations of <1, >10, 5-10, and >50 mM, resp. Inhibition of glucose oxidation was correlated with a reduction in ATP concentration in the spermatozoa. α-Chlorohydrin may act as an antifertility agent by inhibition of sperm glycolysis, but RS-α-chlorohydrin would apparently not be an effective contraceptive in man. However, the glucose metabolism of human spermatozoa was significantly inhibited by <10 mM of S-α-chlorohydrin [60827-45-4].

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called NaRb7(Si4-xGex)2 – Soluble Zintl Phases Containing Heteroatomic Tetrahedral [Si4-xGex]4- Clusters, published in 2013, which mentions a compound: 75732-01-3, Name is Mesitylcopper(I), Molecular C9H11Cu, Computed Properties of C9H11Cu.

The quaternary phases NaRb7(Si4-xGex)2 (x = 1-3) crystallize with an NaRb7Ge8-type structure and contain tetrahedral four-atom clusters that consist of Si and Ge atoms. The quaternary phases possess larger cell volumes with increasing Ge amount The formation of heteroat. [Si4-xGex]4- clusters is indicated by chem. different Si environments, which were analyzed by solid-state 29Si MAS (magic-angle spinning) NMR spectroscopy of a 29Si-enriched NaRb7(Si4-xGex)2 sample with x = 0.5 as well as quantum chem. calculations of the NMR coupling parameters. NaRb7(Si4-xGex)2 represents another rare example of a phase with exclusively tetrahedral clusters that readily dissolves in liquid ammonia. The nature of the heteroat. clusters was further investigated by dissolution of NaRb7(Si4-xGex)2 with x = 2 in liquid ammonia. In the presence of MesCu (Mes = mesityl) and 18-crown-6 as a sequestering agent, crystals with the composition [Rb(18-crown-6)]2Rb2[(MesCu)2(Si4-xGex)](NH3)11 were isolated with x = 2.2(1). [(MesCu)2(Si4-xGex)]4- represents another isomer of a MesCu-stabilized tetrahedral anion and supports the observation that Zintl phases, which contain solely tetrahedranide subunits, represent a new class of soluble Zintl phases.

Computed Properties of C9H11Cu. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about 1,4-Addition of Diorganozincs to α,β-Unsaturated Ketones Catalyzed by a Copper(I)-Sulfonamide Combined System. Author is Kitamura, Masato; Miki, Takashi; Nakano, Keiji; Noyori, Ryoji.

A mixture of CuCN and N-benzylbenzenesulfonamide catalyzes the 1,4-addition of dialkylzincs or diarylzincs (Cu : Zn = 1 : 200 to 1 : 10000) to α,β-unsaturated ketones to give, after aqueous workup, the corresponding β-substituted ketones in nearly quant. yields. A range of cyclic enones having s-cis or s-trans geometries as well as conformationally flexible acyclic enones are usable as substrates. The Et group migrates more readily than the Me and Ph groups. CuOTf, CuO-t-C4H9, and mesitylcopper can be used in place of CuCN. The in situ-formed alkylzinc enolate, prior to aqueous workup, further undergoes an aldol reaction with aldehydes or Pd(0)-assisted coupling with allyl acetate, resulting in regio-controlled, vicinal carbacondensation products. A catalytic cycle is proposed on the basis of a kinetic study and a structural anal. of the zinc enolate product by NMR and mol. weight measurements.

In comparison, the reaction of AgCl with Li[L’] results in the formation of the tri-silver complex [Ag3(L’)3] with Ag···Ag separations of 3.01184(17) Å, 2.95329(17) Å, and 2.92745(16) Å. Attempts to react the parent triazene system L’H with [Cu(mesityl)] resulted in the formation of the novel tri-copper system [Cu3(L’)2(mesityl)].

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:4553-62-2) here.

A chemoenzymic process for the preparation of 1,5-dimethyl-2-piperidone (1,5-DMPD) from 2-methylglutaronitrile (MGN) has been demonstrated. MGN was first hydrolyzed to 4-cyanopentanoic acid (4-CPA) ammonium salt using the nitrilase activity of immobilized Acidovorax facilis 72W cells. The hydrolysis reaction produced 4-CPA ammonium salt with greater than 98% regioselectivity at 100% conversion, and at concentrations of 170-210 g 4-CPA/l. Catalyst productivities of at least 1000 g 4-CPA/g dry cell weight (dcw) of immobilized cells were achieved by recycling the immobilized-cell catalyst in consecutive stirred-batch reactions. After recovery of the immobilized cell catalyst for reuse, the 4-CPA ammonium salt in the aqueous product mixture was directly converted to 1,5-DMPD by low-pressure catalytic hydrogenation in the presence of added methylamine.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (2S)-(+)-3-Chloropropane-1,2-diol, is researched, Molecular C3H7ClO2, CAS is 60827-45-4, about Enhancing the detection sensitivity of trace analysis of pharmaceutical genotoxic impurities by chemical derivatization and coordination ion spray-mass spectrometry.COA of Formula: C3H7ClO2.

Many pharmaceutical genotoxic impurities are neutral mols. Trace level anal. of these neutral analytes is hampered by their poor ionization efficiency in mass spectrometry (MS). Two anal. approaches including chem. derivatization and coordination ion spray-MS were developed to enhance neutral analyte detection sensitivity. The chem. derivatization approach converts analytes into highly ionizable or permanently charged derivatives, which become readily detectable by MS. The coordination ion spray-MS method, on the other hand, improves ionization by forming neutral-ion adducts with metal ions such as Na+, K+, or NH4 + which are introduced into the electrospray ionization source. Both approaches have been proven to be able to enhance the detection sensitivity of neutral pharmaceuticals dramatically. This article demonstrates the successful applications of the two approaches in the anal. of four pharmaceutical genotoxic impurities identified in a single drug development program, of which two are non-volatile alkyl chlorides and the other two are epoxides.

Carbonylation of 2,6-diphenylphenoxocopper(I), tetrameric [(CuOC6H3Ph2)4] (1), results in a [{Cu(OC6H3Ph2)(CO)}2] dimer (2). The parent aryl oxide, [(CuOC6H3Ph2)4], which was prepared from mesitylcopper(I) and 2,6-diphenylphenol, has an approx. planar Cu4O4 core, in which Cu(I) is two-coordinated and Cu-O bonds range from 1.834(7) to 1.865(7) Å. Its carbonylation product 2 is a μ2-phenoxo-bridged dimer, containing three-coordinated Cu(I), with longer Cu-O bonds, viz. 1.953(7)-1.995(7) Å. Cu-C bond lengths in 2 are 1.78(1) and 1.79(1) Å, resp., with both carbonyl C-O distances equal to 1.12(1) Å, and Cu-C-O angles of 174(1) and 179(1)°, resp. Carbonyl stretching frequencies in the IR are 2099, 2103, and 2112 cm-1 for the solid and 2102 cm-1 in toluene solution, and the 13C NMR signal (toluene solution) is at 168 ppm. From comparison with other carbonyl complexes of Cu(I), the Cu-C bond is judged to be predominantly of σ character, with minimal metal → ligand π* contribution.
