Description
CATO manufactures 4-Bromo-5-fluoropyrimidine 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.
4-Bromo-5-fluoropyrimidine (CAS 1003706-87-3) is a high-purity analytical reference standard with the molecular formula C4H2BrFN2 and a molecular weight of 176.97 g/mol.
The molecular framework of 4-Bromo-5-fluoropyrimidine (C4H2BrFN2) is characterized by a nitrile group, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
