4-Methylisobenzofuran-1(3H)-one CAS 2211-83-8

Description

The occurrence of 4-Methylisobenzofuran-1(3H)-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methylisobenzofuran-1(3H)-one (CAS 2211-83-8) is a high-purity analytical reference standard with the molecular formula C9H8O2 and a molecular weight of 148.16 g/mol.

Structurally, 4-Methylisobenzofuran-1(3H)-one (C9H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 148.16 g/mol, it falls into the low-molecular-weight range. 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).

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.
