Krasnova, M. A. published the artcileQuantitative analysis of iodine-containing pharmaceutical preparations by combustion in oxygen, Safety of 2-(3,5-Diiodo-4-oxopyridin-1(4H)-yl)acetic acid, the publication is Farmatsiya (Moscow, Russian Federation) (1969), 18(3), 57-60, database is CAplus and MEDLINE.
Anal. of I-containing (50-69% of I) pharmaceutical preparations by combustion in O utilizes a new modification of the method and a comparison is made with the existing ones. The sample (0.02-0.03 g.) is placed on the Pt grid (initially not in contact with the solution), 10 ml. 2N KOH and 50 ml. H2O are poured into a flask and O bubbled through 5 min. Then the sample is burned (20-30 sec.) and the flask tightly stopped. The content is then shaken (5-6 min.) and allowed to stand for 10 min. more. Br (5 ml.) and AcOH are then added, the solution stirred and 0.3 ml. 85% HCO2H added. After the solution has lost its color, 20 ml. of N H2SO4 and 0.05 g. KI are added, and the flask allowed to stand in dark 5 min. The liberated I is titrated with 0.1N Na2S2O3 (1% starch indicator). The time of anal. is 30 min. The relative error is â?.4%.
Farmatsiya (Moscow, Russian Federation) published new progress about 101-29-1. 101-29-1 belongs to iodides-buliding-blocks, auxiliary class Pyridine,Iodide,Carboxylic acid,Ketone, name is 2-(3,5-Diiodo-4-oxopyridin-1(4H)-yl)acetic acid, and the molecular formula is C7H5I2NO3, Safety of 2-(3,5-Diiodo-4-oxopyridin-1(4H)-yl)acetic acid.
