Chemical Structure
Description
(2R)-3-[(4-Fluorophenyl)sulfonyl]-2-hydroxy-2-methylpropanoic Acid (CAS 890658-79-4), molecular formula C10H11FO5S and molecular weight 262.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2R)-3-[(4-Fluorophenyl)sulfonyl]-2-hydroxy-2-methylpropanoic Acid (C10H11FO5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 262.25 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
