Chemical Structure

Ivosidenib Impurity 3 CAS CATO-C4X-30273 chemical structure

Description

Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Ivosidenib Impurity 3 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a process- or degradation-related impurity, Ivosidenib Impurity 3 (CAS CATO-C4X-30273, C5H11NO5S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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 manufactures Ivosidenib Impurity 3 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.
