Chemical Structure

Repaglinide Impurity O CAS 147770-03-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Repaglinide Impurity O.

CATO supplies Repaglinide Impurity O (CAS 147770-03-4), a pharmacopoeial impurity reference standard (molecular formula C16H23NO, MW 245.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C16H23NO, Repaglinide Impurity O contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 245.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Repaglinide Impurity O 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.
