Chemical Structure

Bisoprolol Impurity 84 CAS CATO-C4X-124784 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 Bisoprolol Impurity 84.

CATO supplies Bisoprolol Impurity 84 (CAS CATO-C4X-124784), a pharmacopoeial impurity reference standard (molecular formula C21H37NO4, MW 367.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C21H37NO4, Bisoprolol Impurity 84 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 367.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Bisoprolol Impurity 84 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
