Dopamine Impurity 40 CAS CATO-C4X-190840

Description

Compared with other compounds in its class, the molecular weight of 297.39 g/mol gives Dopamine Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Dopamine Impurity 40 (CAS CATO-C4X-190840), a pharmacopoeial impurity reference standard (molecular formula C19H23NO2, MW 297.39 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Dopamine Impurity 40 (C19H23NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Dopamine Impurity 40 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.
