Pyridoxine impurity 80 CAS CATO-C4X-187780 chemical structure

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO supplies Pyridoxine impurity 80 (CAS CATO-C4X-187780), a pharmacopoeial impurity reference standard (molecular formula C8H14O3, MW 158.19 g/mol) used for the identification and quantification of trace impurities in APIs.

Pyridoxine impurity 80 (C8H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
