Chemical Structure

2,3-Dihydroxycyclohepta-2,4,6-trienone CAS 34777-04-3 chemical structure

Description

2,3-Dihydroxycyclohepta-2,4,6-trienone (CAS 34777-04-3), molecular formula C7H6O3 and molecular weight 138.12 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, 2,3-Dihydroxycyclohepta-2,4,6-trienone is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.12 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).

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