Chemical Structure
Description
58621-51-5 Ethanone, 1-(2,3-dihydro-2-methyl-5-benzofuranyl)- 5-17-10-00058 (Beilstein Handbook Reference) 5-Acetyl-2-methylcoumaran BRN 0143143 1-(2,3-Dihydro-2-methyl-5-benzofuranyl)ethanone (CAS 58621-51-5), molecular formula C11H18O2 and molecular weight 182.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 58621-51-5 Ethanone, 1-(2,3-dihydro-2-methyl-5-benzofuranyl)- 5-17-10-00058 (Beilstein Handbook Reference) 5-Acetyl-2-methylcoumaran BRN 0143143 1-(2,3-Dihydro-2-methyl-5-benzofuranyl)ethanone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.26 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.
