Luliconazole Impurity 13 CAS CATO-C4X-285313

Description

Compared with other compounds in its class, the molecular weight of 372.29 g/mol gives Luliconazole Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Luliconazole Impurity 13 (CAS CATO-C4X-285313), a pharmacopoeial impurity reference standard (molecular formula C14H11Cl2N3OS2, MW 372.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, Luliconazole Impurity 13 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.29 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.
