Description
CATO supplies 6258-66-8 Benzenemethanethiol, 4-chloro- (9CI) p-Chlorotoluene-alpha-thiol EINECS 228-395-7 NSC 108735 (CAS 6258-66-8), a certified reference material (molecular formula C7H13ClS, MW 164.70 g/mol) for analytical method development and quality control.
The molecular framework of 6258-66-8 Benzenemethanethiol, 4-chloro- (9CI) p-Chlorotoluene-alpha-thiol EINECS 228-395-7 NSC 108735 (C7H13ClS) 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.
