1,2-Difluoro-4-((4-(trans-4-propylcyclohexyl)phenyl)ethynyl)benzene CAS 121118-73-8

Description

The occurrence of 1,2-Difluoro-4-((4-(trans-4-propylcyclohexyl)phenyl)ethynyl)benzene is closely related to fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-Difluoro-4-((4-(trans-4-propylcyclohexyl)phenyl)ethynyl)benzene (CAS 121118-73-8) is a high-purity analytical reference standard with the molecular formula C23H24F2 and a molecular weight of 338.43 g/mol.

Owing to fluorine substitution, a polycyclic aromatic system, 1,2-Difluoro-4-((4-(trans-4-propylcyclohexyl)phenyl)ethynyl)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
