Chemical Structure
Description
p-Tolylsulfur Pentafluoride (C7H7F5S) contains sulfur-containing functionality, fluorine substitution. 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.
p-Tolylsulfur Pentafluoride (CAS 203126-21-0) is a high-purity analytical reference standard with the molecular formula C7H7F5S and a molecular weight of 218.19 g/mol.
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), p-Tolylsulfur Pentafluoride 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.
