1,1,1,3,3,3-Hexafluoropropan-2-yl 4-methylbenzenesulfonate CAS 67674-48-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,1,3,3,3-Hexafluoropropan-2-yl 4-methylbenzenesulfonate.

1,1,1,3,3,3-Hexafluoropropan-2-yl 4-methylbenzenesulfonate (CAS 67674-48-0), molecular formula C10H8F6O3S and molecular weight 322.22 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, an aromatic ring system, 1,1,1,3,3,3-Hexafluoropropan-2-yl 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.22 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
