1-(Difluorophenylmethyl)-3,5-bis(trifluoromethyl)benzene CAS 1138445-31-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 340.21 g/mol gives 1-(Difluorophenylmethyl)-3,5-bis(trifluoromethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(Difluorophenylmethyl)-3,5-bis(trifluoromethyl)benzene (CAS 1138445-31-4), molecular formula C15H8F8 and molecular weight 340.21 g/mol, is a CATO reference standard with documented purity and traceability.

1-(Difluorophenylmethyl)-3,5-bis(trifluoromethyl)benzene (C15H8F8) contains fluorine substitution, a polycyclic aromatic 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-(Difluorophenylmethyl)-3,5-bis(trifluoromethyl)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.
