1-(Difluorophenylmethyl)-2-methylbenzene CAS 1204295-98-6

Description

The occurrence of 1-(Difluorophenylmethyl)-2-methylbenzene is closely related to fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(Difluorophenylmethyl)-2-methylbenzene (CAS 1204295-98-6) is a high-purity analytical reference standard with the molecular formula C14H12F2 and a molecular weight of 218.24 g/mol.

The molecular framework of 1-(Difluorophenylmethyl)-2-methylbenzene (C14H12F2) is characterized by fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
