3-Fluoro-5-hydroxypyridine CAS 209328-55-2 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

3-Fluoro-5-hydroxypyridine (CAS 209328-55-2), molecular formula C5H4FNO and molecular weight 113.09 g/mol, is a CATO reference standard with documented purity and traceability.

3-Fluoro-5-hydroxypyridine (C5H4FNO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
