Chemical Structure

Etomidate impurity 59 CAS CATO-C4X-188459 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 Etomidate impurity 59.

CATO supplies Etomidate impurity 59 (CAS CATO-C4X-188459), a pharmacopoeial impurity reference standard (molecular formula C16H20N2O2, MW 272.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Etomidate impurity 59 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.34 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.

As a certified reference material (CRM), Etomidate 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.
