Chemical Structure

Lornoxicam Impurity 27 CAS CATO-C4X-201627 chemical structure

Description

CATO supplies Lornoxicam Impurity 27 (CAS CATO-C4X-201627), a pharmacopoeial impurity reference standard (molecular formula C10H11Cl2NO6S2, MW 376.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Lornoxicam Impurity 27 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
