Description
CATO manufactures Bromocriptine EP Impurity D 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.
Bromocriptine EP Impurity D (CAS 478-83-1) is a certified pharmaceutical impurity reference standard with the molecular formula C16H15BrN2O2 and a molecular weight of 347.21 g/mol.
Based on its molecular formula C16H15BrN2O2, Bromocriptine EP Impurity D contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 347.21 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.
