Chemical Structure

(3,5-Difluoro-2-methylphenyl)methanol CAS 1378666-27-3 chemical structure

Description

The occurrence of (3,5-Difluoro-2-methylphenyl)methanol is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3,5-Difluoro-2-methylphenyl)methanol (CAS 1378666-27-3), molecular formula C8H8F2O and molecular weight 158.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3,5-Difluoro-2-methylphenyl)methanol (C8H8F2O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 158.15 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
