Vigabatrin Impurity 9 CAS 71107-20-5 chemical structure

Description

CATO supplies Vigabatrin Impurity 9 (CAS 71107-20-5), a pharmacopoeial impurity reference standard (molecular formula C7H9NO3, MW 155.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Vigabatrin Impurity 9 (C7H9NO3) contains an amino-acid-derived structure, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Vigabatrin Impurity 9 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
