Chemical Structure

Busulfan Impurity 20 CAS 31465-25-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 176.16 g/mol gives Busulfan Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Busulfan Impurity 20 (CAS 31465-25-5, C4H9O4SNa) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Busulfan Impurity 20 (C4H9O4SNa) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 176.16 g/mol, it falls into the medium-molecular-weight range.

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 Busulfan Impurity 20 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.
