Compared with other compounds in its class, the molecular weight of 441.45 g/mol gives Salbutamol EP Impurity G(Trifluoroacetic Acid) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Salbutamol EP Impurity G(Trifluoroacetic Acid) (CAS CATO-C4X-117662), a pharmacopoeial impurity reference standard (molecular formula C20H25NO3C2HF3O2, MW 441.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C20H25NO3C2HF3O2, Salbutamol EP Impurity G(Trifluoroacetic Acid) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 441.45 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).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Salbutamol EP Impurity G(Trifluoroacetic Acid) 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.
