Chemical Structure

(R)-P-Chlorophenyl phenyl sulfoxide CAS 1016-82-6 chemical structure

Description

(R)-P-Chlorophenyl phenyl sulfoxide (CAS 1016-82-6) is a high-purity analytical reference standard with the molecular formula C12H9ClOS and a molecular weight of 236.72 g/mol.

The molecular framework of (R)-P-Chlorophenyl phenyl sulfoxide (C12H9ClOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
