Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-bromo-1,4-dihydropyridin-4-one.
2-bromo-1,4-dihydropyridin-4-one (CAS 54855-83-3), molecular formula C5H8BrNO and molecular weight 178.03 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H8BrNO, 2-bromo-1,4-dihydropyridin-4-one contains an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-bromo-1,4-dihydropyridin-4-one 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.
