Compared with other compounds in its class, the molecular weight of 290.20 g/mol gives Terbutaline Impurity 31 HBr distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Terbutaline Impurity 31 HBr (CAS 2459974-80-0), a pharmacopoeial impurity reference standard (molecular formula C12H19NO2HBr, MW 290.20 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C12H19NO2HBr, Terbutaline Impurity 31 HBr contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Terbutaline Impurity 31 HBr 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.
