Methylbenzofuran-2(3H)-one CAS 111783-85-8

Description

Compared with other compounds in its class, the molecular weight of 148.16 g/mol gives Methylbenzofuran-2(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methylbenzofuran-2(3H)-one (CAS 111783-85-8), molecular formula C9H8O2 and molecular weight 148.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Methylbenzofuran-2(3H)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Methylbenzofuran-2(3H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
