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 1-(Chloro(4-fluorophenyl)(phenyl)methyl)-2-fluorobenzene.
1-(Chloro(4-fluorophenyl)(phenyl)methyl)-2-fluorobenzene (CAS 128092-75-1), molecular formula C19H13ClF2 and molecular weight 314.76 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Chloro(4-fluorophenyl)(phenyl)methyl)-2-fluorobenzene (C19H13ClF2) contains fluorine/chlorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(Chloro(4-fluorophenyl)(phenyl)methyl)-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.
