Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(trifluoromethoxy)ethyl 4-methylbenzenesulfonate.
CATO supplies 2-(trifluoromethoxy)ethyl 4-methylbenzenesulfonate (CAS 1897449-20-5), a certified reference material (molecular formula C10H11F3O4S, MW 284.25 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-(trifluoromethoxy)ethyl 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.25 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.
