Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.32 g/mol gives Terbutaline EP Impurity B Formate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Terbutaline EP Impurity B Formate (CAS 94120-05-5(Free Base)) is a certified pharmaceutical impurity reference standard with the molecular formula C13H19NO3CH2O2 and a molecular weight of 283.32 g/mol.
Based on its molecular formula C13H19NO3CH2O2, Terbutaline EP Impurity B Formate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 283.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Terbutaline EP Impurity B Formate 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.
