Chemical Structure
Description
The occurrence of 2,3,4,5,6-Pentafluoro-N-(4-hydroxy-3-(phenylthio)naphthalen-1-yl)benzenesulfonamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3,4,5,6-Pentafluoro-N-(4-hydroxy-3-(phenylthio)naphthalen-1-yl)benzenesulfonamide (CAS 1809581-87-0) is a high-purity analytical reference standard with the molecular formula C22H12F5NO3S2 and a molecular weight of 497.46 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2,3,4,5,6-Pentafluoro-N-(4-hydroxy-3-(phenylthio)naphthalen-1-yl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 497.46 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.
As a certified reference material (CRM), 2,3,4,5,6-Pentafluoro-N-(4-hydroxy-3-(phenylthio)naphthalen-1-yl)benzenesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
