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 process- or degradation-related impurity, Thiamine Impurity N2 (CAS 15678-01-0, C5H10O2S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Thiamine Impurity N2 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO manufactures Thiamine Impurity N2 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.
