Chemical Structure

Decitabine Impurity 1 (alpha-Isomer) CAS 51255-17-5 chemical structure

Description

The occurrence of Decitabine Impurity 1 (alpha-Isomer) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Decitabine Impurity 1 (alpha-Isomer) (CAS 51255-17-5), a pharmacopoeial impurity reference standard (molecular formula C6H12O4, MW 148.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Decitabine Impurity 1 (alpha-Isomer) (C6H12O4) contains 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.

As a certified reference material (CRM), Decitabine Impurity 1 (alpha-Isomer) 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.
