Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 524.51 g/mol gives Mirabegron Impurity 146 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Mirabegron Impurity 146 (CAS CATO-C4X-1032146), a pharmacopoeial impurity reference standard (molecular formula C21H22N4O3SC2HF3O2, MW 524.51 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Mirabegron Impurity 146 (C21H22N4O3SC2HF3O2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 524.51 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Mirabegron Impurity 146 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.
