Adefovir Impurity 36 CAS 683-08-9 chemical structure

Description

CATO manufactures Adefovir Impurity 36 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

As a process- or degradation-related impurity, Adefovir Impurity 36 (CAS 683-08-9, C5H13O3P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Adefovir Impurity 36 (C5H13O3P) contains a phosphonate group, 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.

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.
