Chemical Structure

Mirabegron Impurity 71 CAS 7369-50-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 151.16 g/mol gives Mirabegron Impurity 71 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Mirabegron Impurity 71 (CAS 7369-50-8), a pharmacopoeial impurity reference standard (molecular formula C8H9NO2, MW 151.16 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Mirabegron Impurity 71 (C8H9NO2) is characterized by an amino-acid-derived structure, 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. 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), Mirabegron Impurity 71 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.
