Chemical Structure
Description
The occurrence of 5-bromo-6-fluoropyridin-3-ol is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-bromo-6-fluoropyridin-3-ol (CAS 186593-54-4), molecular formula C5H9BrFNO and molecular weight 198.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-bromo-6-fluoropyridin-3-ol (C5H9BrFNO) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
CATO manufactures 5-bromo-6-fluoropyridin-3-ol 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.
