Chemical Structure

Luliconazole impurity 18 CAS CATO-C4X-285318 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 225.50 g/mol gives Luliconazole impurity 18 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Luliconazole impurity 18 (CAS CATO-C4X-285318), a pharmacopoeial impurity reference standard (molecular formula C8H7Cl3O, MW 225.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Luliconazole impurity 18 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.50 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).

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.

CATO manufactures Luliconazole impurity 18 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
