Chemical Structure
Description
5-fluoro-1,3-benzothiazole-2-carboxylic acid (CAS 139425-47-1) is a high-purity analytical reference standard with the molecular formula C8H12FNO2S and a molecular weight of 205.25 g/mol.
Structurally, 5-fluoro-1,3-benzothiazole-2-carboxylic acid (C8H12FNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 205.25 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
