Dapagliflozin Impurity 223 CAS CATO-C4X-1138223

Description

The occurrence of Dapagliflozin Impurity 223 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 Dapagliflozin Impurity 223 (CAS CATO-C4X-1138223), a pharmacopoeial impurity reference standard (molecular formula C15H34O6Si3, MW 394.69 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Dapagliflozin Impurity 223 (C15H34O6Si3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 394.69 g/mol, it falls into the moderately-high-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 Dapagliflozin Impurity 223 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.
