Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methoxy-2-(methylsulfonyl)benzoic acid.
5-Methoxy-2-(methylsulfonyl)benzoic acid (CAS 873986-56-2), molecular formula C9H10O5S and molecular weight 230.24 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, an aromatic ring system, 5-Methoxy-2-(methylsulfonyl)benzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.24 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.
