Chemical Structure

1-Ethylnaphtho[2,1-b]furan-2(1H)-one CAS 496783-32-5 chemical structure

Description

CATO manufactures 1-Ethylnaphtho[2,1-b]furan-2(1H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

1-Ethylnaphtho[2,1-b]furan-2(1H)-one (CAS 496783-32-5) is a high-purity analytical reference standard with the molecular formula C14H12O2 and a molecular weight of 212.24 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1-Ethylnaphtho[2,1-b]furan-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
