Chemical Structure
Description
The occurrence of 2-Bromo-6-fluoropyridin-4-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.
2-Bromo-6-fluoropyridin-4-ol (CAS 1256804-32-6), molecular formula C5H3BrFNO and molecular weight 191.99 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Bromo-6-fluoropyridin-4-ol (C5H3BrFNO) contains an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 191.99 g/mol, it falls into the medium-molecular-weight range. 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 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-6-fluoropyridin-4-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.
