Chemical Structure
Description
The occurrence of Trifluoromethanesulfonic Acid is closely related to a sulfone group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Trifluoromethanesulfonic Acid (CAS 1493-13-6), molecular formula CHF3O3S and molecular weight 150.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, fluorine substitution, Trifluoromethanesulfonic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Trifluoromethanesulfonic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
