Chemical Structure

4-Methylisochroman-1,3-dione CAS 4780-07-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4-Methylisochroman-1,3-dione (CAS 4780-07-8), a certified reference material (molecular formula C10H8O3, MW 176.17 g/mol) for analytical method development and quality control.

The molecular framework of 4-Methylisochroman-1,3-dione (C10H8O3) 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).

As a certified reference material (CRM), 4-Methylisochroman-1,3-dione 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.
