Chemical Structure

Dexmedetomidine Impurity 33 CAS 40243-75-2 chemical structure

Description

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 supplies Dexmedetomidine Impurity 33 (CAS 40243-75-2), a pharmacopoeial impurity reference standard (molecular formula C10H12, MW 132.20 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an aromatic ring system, Dexmedetomidine Impurity 33 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Dexmedetomidine Impurity 33 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.
