Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, 4,5-Difluoropyridine-2-thiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
4,5-Difluoropyridine-2-thiol (CAS 1806332-29-5), molecular formula C5H3F2NS and molecular weight 147.15 g/mol, is a CATO reference standard with documented purity and traceability.
