Chemical Structure
Description
3-Nitro-4-(phenylthio)benzyl 2,6-difluorobenzoate (CAS 320424-18-8), molecular formula C20H13F2NO4S and molecular weight 401.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 3-Nitro-4-(phenylthio)benzyl 2,6-difluorobenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.38 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Nitro-4-(phenylthio)benzyl 2,6-difluorobenzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
