Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methoxy-5-(pentafluoro-λ6-sulfanyl)benzoic acid.
2-Methoxy-5-(pentafluoro-λ6-sulfanyl)benzoic acid (CAS 1448319-14-9), molecular formula C8H7F5O3S and molecular weight 278.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Methoxy-5-(pentafluoro-λ6-sulfanyl)benzoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.20 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-Methoxy-5-(pentafluoro-λ6-sulfanyl)benzoic acid 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.
