Ramelteon Impurity 59 CAS CATO-C4X-262259 chemical structure

Description

As a certified reference material (CRM), Ramelteon Impurity 59 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.

CATO supplies Ramelteon Impurity 59 (CAS CATO-C4X-262259), a pharmacopoeial impurity reference standard (molecular formula C17H23NO2, MW 273.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Ramelteon Impurity 59 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
