Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-DICHLOROHEXAFLUORO-2-BUTENE.
2,3-DICHLOROHEXAFLUORO-2-BUTENE (CAS 303-04-8), molecular formula C4Cl2F6 and molecular weight 232.94 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-DICHLOROHEXAFLUORO-2-BUTENE (C4Cl2F6) contains fluorine/chlorine 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.
CATO manufactures 2,3-DICHLOROHEXAFLUORO-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.
