Chemical Structure

4-Methoxy-2,3-dimethylphenol CAS 35355-33-0 chemical structure

Description

4-Methoxy-2,3-dimethylphenol (CAS 35355-33-0) is a high-purity analytical reference standard with the molecular formula C9H12O2 and a molecular weight of 152.19 g/mol.

Based on its molecular formula C9H12O2, 4-Methoxy-2,3-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 152.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
