Difenidol Impurity 6 HCl CAS CATO-C4X-22276

Description

Compared with other compounds in its class, the molecular weight of 242.58 g/mol gives Difenidol Impurity 6 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Difenidol Impurity 6 HCl (CAS CATO-C4X-22276), a pharmacopoeial impurity reference standard (molecular formula C8H16BrNHCl, MW 242.58 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to chlorine/bromine substitution, Difenidol Impurity 6 HCl is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.58 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.

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), Difenidol Impurity 6 HCl 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.
