Quick specific assay for aspirin: Quick specific assay for aspirin. Theimer, Edgar E.; Ciurczak, Emil W. (Copper Lab., Inc., Cedar Knolls, N.Chemicals with cas numbers 69-65-8 and 50-78-2 also play role. J., USA). J. Pharm. Sci., 66(1), 139-40 (English) 1977. CODEN: JPMSAE. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) O-dianisidine-HCl, Me2CO, H2O2, aspirin (I) [50-78-2], and Na3PO4 were mixed in the listed order and the resultant color detd. colorimetrically at 445 nm. The absorbance was linear and directly proportional to concn. over a concn. range of 0.1-1.6 mg I/mL. Salicylsalicylic acid [552-94-3] and to a lesser extent propylene glycol diacetate [623-84-7] and acetylated mannitol interfered with the detn. while salicylic acid [69-72-7], caffeine [58-08-2], phenacetin [62-44-2], acetaminophen [103-90-2], and codeine [76-57-3] did not. The results obtained with this method compared favorably with those obtained with a chromatog. method analogous to the NF procedure. .

High-pressure liquid chromatographic determination of immunogenic contaminants of acetylsalicylic acid preparations: High-pressure liquid chromatographic determination of immunogenic contaminants of acetylsalicylic acid preparations. Bundgaard, Hans (Dep. Pharm., R. Dan. Sch. Pharm., Copenhagen, Den.).Chemicals with cas numbers 50-78-2 and 530-75-6 also play role. Arch. Pharm. Chemi, Sci. Ed., 4(6), 103-13 Published in: Arch. Pharm. Chemi 83(26), 1173-83 (English) 1976. CODEN: AVPCCS. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) A high-pressure liq. chromatog. (HPLC) procedure was developed for the quant. detn. of acetylsalicylic anhydride [1466-82-6] and acetylsalicylsalicylic acid [530-75-6] in acetylsalicylic acid (I) [50-78-2] bulk substance and pharmaceutical formulations. The method involves sepn. of the acid and its contaminants by adsorption chromatog. on a microparticulate silica gel column in <8 min and allows simultaneous quantitation of salicylic acid [69-72-7]. The method was applied to anal. of a large no. of com. I samples and formulations. In a few of these prepns. small amts. of 3 other contaminants were detected. On the basis of their chromatog. behavior these addnl. impurities are assumed to be salicylsalicylic acid [552-94-3], p-acetoxybenzoic acid [2345-34-8], and cis-disalicylide [486-58-8]. Evidence is presented that the immunogenic contaminants, acetylsalicylic anhydride and acetylsalicylsalicylic acid, arise as side-products during the synthesis of acetylsalicylic acid. .
