Mirabegron Impurity 69 CAS CATO-C4X-103269

Description

Compared with other compounds in its class, the molecular weight of 285.29 g/mol gives Mirabegron Impurity 69 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Mirabegron Impurity 69 (CAS CATO-C4X-103269), a pharmacopoeial impurity reference standard (molecular formula C16H15NO4, MW 285.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Mirabegron Impurity 69 (C16H15NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 285.29 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
