4-Chloro-2-fluorobenzenesulfinic acid sodium salt CAS 1233505-92-4

Description

The occurrence of 4-Chloro-2-fluorobenzenesulfinic acid sodium salt is closely related to a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-2-fluorobenzenesulfinic acid sodium salt (CAS 1233505-92-4) is a high-purity analytical reference standard with the molecular formula C6H3ClFO2SNa and a molecular weight of 216.59 g/mol.

Owing to a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 4-Chloro-2-fluorobenzenesulfinic acid sodium salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
