Some common heterocyclic compound, 19230-50-3, name is 2-Iodo-5-nitrobenzoic acid, molecular formula is C7H4INO4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Formula: C7H4INO4
I. 2-Iodo-5-Nitro-Benzamide 2-iodo-5-nitro-benzamide was synthesised by the method previously described for 4-iodo-5-nitro-benzamide using 2-iodo-5-nitro benzoic acid (Chemica Alta Ltd., Edmonton, Alberta, Canada) as the starting material. 1 H NMR Spectrum, in DMSO-d6 delta (ppm) values relative to TMS: 7.742 (1H, singlet); 7.943 (1H, doublet of doublts, J=8.26 Hz, J=2.58 Hz); 8.034 (1H, singlet), 8.064 (1H, doublet, J=2.94 Hz); and 8.191 (1H, doublet, J=8.46 Hz). Mass Spectrum: Low resolution electron impact spectrum (m/z): 292 (M+), 276, 230, 202, 165, 127, 91, 75, 63. High resolution measurement of M+: Calculated for C7 H5 IN2 O3: 291.934494; found: 291.934149 (deviation=1.2 ppm).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 19230-50-3, its application will become more common.
