Description
CATO manufactures 4-Iodo-1,1,1,3-tetrafluoro-2-butene 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.
CATO supplies 4-Iodo-1,1,1,3-tetrafluoro-2-butene (CAS 933668-33-8), a certified reference material (molecular formula C4H3F4I, MW 253.96 g/mol) for analytical method development and quality control.
4-Iodo-1,1,1,3-tetrafluoro-2-butene (C4H3F4I) contains fluorine/iodine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
