Chemical Structure

Regadenoson Impurity 25 CAS 5404-92-2 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 Regadenoson Impurity 25 (CAS 5404-92-2), a pharmacopoeial impurity reference standard (molecular formula C5H7N7, MW 165.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C5H7N7, Regadenoson Impurity 25 contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 165.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 manufactures Regadenoson Impurity 25 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.
