Chemical Structure

6-Acetyl-4-butyl-7-hydroxy-8-methyl-2H-chromen-2-one CAS 951989-05-2 chemical structure

Description

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.

6-Acetyl-4-butyl-7-hydroxy-8-methyl-2H-chromen-2-one (CAS 951989-05-2) is a high-purity analytical reference standard with the molecular formula C16H18O4 and a molecular weight of 274.31 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 6-Acetyl-4-butyl-7-hydroxy-8-methyl-2H-chromen-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
