Etomidate Impurity 65 CAS 83763-26-2

Description

Compared with other compounds in its class, the molecular weight of 263.29 g/mol gives Etomidate Impurity 65 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Etomidate Impurity 65 (CAS 83763-26-2), a pharmacopoeial impurity reference standard (molecular formula C14H17NO4, MW 263.29 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 65 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 65 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.
