Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,2-Difluorovinyl)-2,3,4,5,6-pentafluoro-benzene.
1-(2,2-Difluorovinyl)-2,3,4,5,6-pentafluoro-benzene (CAS 653-19-0), molecular formula C8HF7 and molecular weight 230.08 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2,2-Difluorovinyl)-2,3,4,5,6-pentafluoro-benzene (C8HF7) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-(2,2-Difluorovinyl)-2,3,4,5,6-pentafluoro-benzene 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.
