Chemical Structure

Evocalcet Impurity 74 CAS CATO-C4X-248574 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Evocalcet Impurity 74 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 596.80 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).

CATO supplies Evocalcet Impurity 74 (CAS CATO-C4X-248574), a pharmacopoeial impurity reference standard (molecular formula C40H44N4O, MW 596.80 g/mol) used for the identification and quantification of trace impurities in APIs.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
