Chemical Structure

2,6-Diacetyl-3,5-dimethylphenol CAS 66634-65-9 chemical structure

Description

The occurrence of 2,6-Diacetyl-3,5-dimethylphenol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,6-Diacetyl-3,5-dimethylphenol (CAS 66634-65-9) is a high-purity analytical reference standard with the molecular formula C12H14O3 and a molecular weight of 206.24 g/mol.

Based on its molecular formula C12H14O3, 2,6-Diacetyl-3,5-dimethylphenol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
