Description
CATO manufactures 1-(Difluoromethyl)-4-methylnaphthalene 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.
1-(Difluoromethyl)-4-methylnaphthalene (CAS 1221272-85-0) is a high-purity analytical reference standard with the molecular formula C12H10F2 and a molecular weight of 192.20 g/mol.
1-(Difluoromethyl)-4-methylnaphthalene (C12H10F2) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
