Chemical Structure

4-Methyl-3-(naphthalen-1-yl)isobenzofuran-1(3H)-one CAS 86785-13-9 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-Methyl-3-(naphthalen-1-yl)isobenzofuran-1(3H)-one (CAS 86785-13-9), a certified reference material (molecular formula C19H14O2, MW 274.31 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 4-Methyl-3-(naphthalen-1-yl)isobenzofuran-1(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.31 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).

As a certified reference material (CRM), 4-Methyl-3-(naphthalen-1-yl)isobenzofuran-1(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.
