Chemical Structure

4-Butyl-7-hydroxy-8-methyl-2h-chromen-2-one CAS 405918-90-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 232.28 g/mol gives 4-Butyl-7-hydroxy-8-methyl-2h-chromen-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Butyl-7-hydroxy-8-methyl-2h-chromen-2-one (CAS 405918-90-3), a certified reference material (molecular formula C14H16O3, MW 232.28 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4-Butyl-7-hydroxy-8-methyl-2h-chromen-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
