Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.20 g/mol gives 1-(2-Hydroxy-4-methoxy-6-methylphenyl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Hydroxy-4-methoxy-6-methylphenyl)ethan-1-one (CAS 6540-66-5) is a high-purity analytical reference standard with the molecular formula C10H12O3 and a molecular weight of 180.20 g/mol.
The molecular framework of 1-(2-Hydroxy-4-methoxy-6-methylphenyl)ethan-1-one (C10H12O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
