Chemical Structure

Sarecycline Impurity 3 CAS CATO-C4X-27983 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 540.31 g/mol gives Sarecycline Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sarecycline Impurity 3 (CAS CATO-C4X-27983), a pharmacopoeial impurity reference standard (molecular formula C21H21IN2O7, MW 540.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C21H21IN2O7, Sarecycline Impurity 3 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 540.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Sarecycline Impurity 3 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.
