Description
20611-21-6 Ethanol, 2-(phenylsulfonyl)- 4-06-00-01494 (Beilstein Handbook Reference) 2-(Benzenesulfonyl)ethanol BRN 1952741 Fenyl-beta-hydroxyethylsulfon [Czech] Fenyl-2-hydroxyethylsulfon [Czech] 2-(Phenylsulfonyl)ethanol Fenyl-2-hydroxyethylsulfon Fenyl-beta-hydroxyethylsulfon (CAS 20611-21-6), molecular formula C8H16O3S and molecular weight 192.28 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, 20611-21-6 Ethanol, 2-(phenylsulfonyl)- 4-06-00-01494 (Beilstein Handbook Reference) 2-(Benzenesulfonyl)ethanol BRN 1952741 Fenyl-beta-hydroxyethylsulfon [Czech] Fenyl-2-hydroxyethylsulfon [Czech] 2-(Phenylsulfonyl)ethanol Fenyl-2-hydroxyethylsulfon Fenyl-beta-hydroxyethylsulfon is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
