Chemical Structure
Description
The molecular framework of 3-Hexyl-7,8-dihydroxy-4-methyl-2h-chromen-2-one (C16H20O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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).
3-Hexyl-7,8-dihydroxy-4-methyl-2h-chromen-2-one (CAS 924775-32-6) is a high-purity analytical reference standard with the molecular formula C16H20O4 and a molecular weight of 276.33 g/mol.
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.
