Chemical Structure

Simvastatin EP Impurity G CAS 1449248-72-9 chemical structure

Description

The occurrence of Simvastatin EP Impurity G is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Simvastatin EP Impurity G (CAS 1449248-72-9), a pharmacopoeial impurity reference standard (molecular formula C25H36O5, MW 416.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Simvastatin EP Impurity G (C25H36O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Simvastatin EP Impurity G 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.
