Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,2,3,3,4,4-Hexafluorobutyric acid (CAS 679-12-9), a certified reference material (molecular formula C4H2F6O2, MW 196.05 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2,2,3,3,4,4-Hexafluorobutyric acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.05 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.
CATO manufactures 2,2,3,3,4,4-Hexafluorobutyric 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.
