3,4-Difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl CAS 134412-17-2

Description

The occurrence of 3,4-Difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl is closely related to fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,4-Difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl (CAS 134412-17-2), molecular formula C23H28F2 and molecular weight 342.47 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine substitution, a polycyclic aromatic system, 3,4-Difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.47 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
