2-Chloroethyl Ethyl Sulfide CAS 693-07-2 chemical structure

Description

2-Chloroethyl Ethyl Sulfide (CAS 693-07-2), molecular formula C4H9ClS and molecular weight 124.63 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Chloroethyl Ethyl Sulfide (C4H9ClS) is characterized by sulfur-containing functionality, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
