Luliconazole impurity 19 CAS CATO-C4X-285319

Description

The occurrence of Luliconazole impurity 19 is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Luliconazole impurity 19 (CAS CATO-C4X-285319) is a certified pharmaceutical impurity reference standard with the molecular formula C11H13Cl3O and a molecular weight of 267.58 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Luliconazole impurity 19 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 267.58 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.

As a certified reference material (CRM), Luliconazole impurity 19 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.
