5-Chloro-2-methoxybenzene-1-thiol (CAS 768-13-8), molecular formula C7H7ClOS and molecular weight 174.65 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-2-methoxybenzene-1-thiol (C7H7ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
