Chemical Structure
Description
2-{[(2,4-difluorophenyl)carbamoyl]methanesulfinyl}acetic acid (CAS 338793-83-2) is a high-purity analytical reference standard with the molecular formula C10H9F2NO4S and a molecular weight of 277.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2-{[(2,4-difluorophenyl)carbamoyl]methanesulfinyl}acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.24 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
