Demeclocycline EP Impurity A CAS 987-02-0

Description

Compared with other compounds in its class, the molecular weight of 430.41 g/mol gives Demeclocycline EP Impurity A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Demeclocycline EP Impurity A (CAS 987-02-0), a pharmacopoeial impurity reference standard (molecular formula C21H22N2O8, MW 430.41 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Demeclocycline EP Impurity A (C21H22N2O8) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 Demeclocycline EP Impurity A 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.
