Description
As a certified reference material (CRM), Mirabegron Impurity 142 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.
CATO supplies Mirabegron Impurity 142 (CAS CATO-C4X-1032142), a pharmacopoeial impurity reference standard (molecular formula C26H28N6O3S2C2HF3O2, MW 650.69 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C26H28N6O3S2C2HF3O2, Mirabegron Impurity 142 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 650.69 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.
