Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Meclozine Dihydrochloride EP Impurity C is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 216.66 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).
CATO supplies Meclozine Dihydrochloride EP Impurity C (CAS 134-85-0), a pharmacopoeial impurity reference standard (molecular formula C13H9ClO, MW 216.66 g/mol) used for the identification and quantification of trace impurities in APIs.
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 Meclozine Dihydrochloride EP Impurity C 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.
