Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Difluoromethoxy)-2-fluorobenzene.
1-(Difluoromethoxy)-2-fluorobenzene (CAS 97963-49-0), molecular formula C7H5F3O and molecular weight 162.11 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Difluoromethoxy)-2-fluorobenzene (C7H5F3O) contains a hydroxyl group, an ether linkage, 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-(Difluoromethoxy)-2-fluorobenzene 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.
