Chemical Structure
Description
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.
(1r)-1-(4-Methanesulfonylphenyl)ethan-1-ol (CAS 726192-01-4), molecular formula C9H12O3S and molecular weight 200.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1r)-1-(4-Methanesulfonylphenyl)ethan-1-ol (C9H12O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
