Chemical Structure

1-(2-hydroxy-3,4-dimethylphenyl)ethan-1-one CAS 5384-55-4 chemical structure

Description

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.

1-(2-hydroxy-3,4-dimethylphenyl)ethan-1-one (CAS 5384-55-4) is a high-purity analytical reference standard with the molecular formula C10H12O2 and a molecular weight of 164.20 g/mol.

1-(2-hydroxy-3,4-dimethylphenyl)ethan-1-one (C10H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
