Chemical Structure

7-Methylbenzofuran-3(2H)-one CAS 669-04-5 chemical structure

Description

As a certified reference material (CRM), 7-Methylbenzofuran-3(2H)-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.

CATO supplies 7-Methylbenzofuran-3(2H)-one (CAS 669-04-5), a certified reference material (molecular formula C9H8O2, MW 148.16 g/mol) for analytical method development and quality control.

The molecular framework of 7-Methylbenzofuran-3(2H)-one (C9H8O2) 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 the polarity and ionization state of its functional groups, 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.
