Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Difluoromethoxy-3-fluorothiophenol.
CATO supplies 4-Difluoromethoxy-3-fluorothiophenol (CAS 1806305-26-9), a certified reference material (molecular formula C7H5F3OS, MW 194.17 g/mol) for analytical method development and quality control.
4-Difluoromethoxy-3-fluorothiophenol (C7H5F3OS) 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), 4-Difluoromethoxy-3-fluorothiophenol 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.
