Description

Compared with other compounds in its class, the molecular weight of 162.19 g/mol gives 2-Methyl-3,4-dihydro-2H-1-benzopyran-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-3,4-dihydro-2H-1-benzopyran-4-one (CAS 5631-75-4) is a high-purity analytical reference standard with the molecular formula C10H10O2 and a molecular weight of 162.19 g/mol.

The molecular framework of 2-Methyl-3,4-dihydro-2H-1-benzopyran-4-one (C10H10O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
