(E)-1-[4-(Trifluoromethyl)phenyl]-2-(3,5-dichlorophenyl)ethene CAS 688348-33-6 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 (E)-1-[4-(Trifluoromethyl)phenyl]-2-(3,5-dichlorophenyl)ethene.

(E)-1-[4-(Trifluoromethyl)phenyl]-2-(3,5-dichlorophenyl)ethene (CAS 688348-33-6) is a high-purity analytical reference standard with the molecular formula C15H9Cl2F3 and a molecular weight of 317.13 g/mol.

(E)-1-[4-(Trifluoromethyl)phenyl]-2-(3,5-dichlorophenyl)ethene (C15H9Cl2F3) 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 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (E)-1-[4-(Trifluoromethyl)phenyl]-2-(3,5-dichlorophenyl)ethene 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.
