3-(P-tolylthio)propane-1-sulfonyl chloride CAS 1375068-13-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(P-tolylthio)propane-1-sulfonyl chloride.

3-(P-tolylthio)propane-1-sulfonyl chloride (CAS 1375068-13-5), molecular formula C10H13ClO2S2 and molecular weight 264.79 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(P-tolylthio)propane-1-sulfonyl chloride (C10H13ClO2S2) is characterized by a sulfone group, a carboxylic acid group, 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.
