Chemical Structure

Epinephrine /Adrenaline Impurity 56 CAS 25015-92-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Epinephrine /Adrenaline Impurity 56.

CATO supplies Epinephrine /Adrenaline Impurity 56 (CAS 25015-92-3), a pharmacopoeial impurity reference standard (molecular formula C8H7ClO3, MW 186.59 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C8H7ClO3, Epinephrine /Adrenaline Impurity 56 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.59 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).

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 Epinephrine /Adrenaline Impurity 56 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.
