Chemical Structure

Enarodustat Impurity 3 CAS CATO-C4X-32283 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 Enarodustat Impurity 3.

CATO supplies Enarodustat Impurity 3 (CAS CATO-C4X-32283), a pharmacopoeial impurity reference standard (molecular formula C7H3Cl2N3O2, MW 232.02 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Enarodustat Impurity 3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.02 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Enarodustat 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.
