Chemical Structure

Busulfan Impurity 12 CAS CATO-C4X-145512 chemical structure

Description

As a certified reference material (CRM), Busulfan Impurity 12 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.

CATO supplies Busulfan Impurity 12 (CAS CATO-C4X-145512), a pharmacopoeial impurity reference standard (molecular formula C10H22O7S2, MW 318.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C10H22O7S2, Busulfan Impurity 12 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 318.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
