Description
(2-Fluoro-4-methoxyphenyl)methanethiol (CAS 357613-01-5), molecular formula C8H9FOS and molecular weight 172.22 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Fluoro-4-methoxyphenyl)methanethiol (C8H9FOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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.
As a certified reference material (CRM), (2-Fluoro-4-methoxyphenyl)methanethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
