Chemical Structure

Urapidil Impurity 61 HCl CAS 1081534-21-5 chemical structure

Description

CATO manufactures Urapidil Impurity 61 HCl 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.

CATO supplies Urapidil Impurity 61 HCl (CAS 1081534-21-5), a pharmacopoeial impurity reference standard (molecular formula C6H13Cl2NHCl, MW 206.54 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Urapidil Impurity 61 HCl (C6H13Cl2NHCl) is characterized by chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
