4-ethoxybenzene-1-sulfonyl fluoride CAS 402-56-2

Description

The occurrence of 4-ethoxybenzene-1-sulfonyl fluoride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-ethoxybenzene-1-sulfonyl fluoride (CAS 402-56-2), molecular formula C8H9FO3S and molecular weight 204.22 g/mol, is a CATO reference standard with documented purity and traceability.

4-ethoxybenzene-1-sulfonyl fluoride (C8H9FO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

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.
