Chemical Structure

1,4-Dihydro-5,8-dimethoxy-1,4-epoxynaphthalene CAS 26002-73-3 chemical structure

Description

The occurrence of 1,4-Dihydro-5,8-dimethoxy-1,4-epoxynaphthalene is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,4-Dihydro-5,8-dimethoxy-1,4-epoxynaphthalene (CAS 26002-73-3), molecular formula C12H12O3 and molecular weight 204.22 g/mol, is a CATO reference standard with documented purity and traceability.

1,4-Dihydro-5,8-dimethoxy-1,4-epoxynaphthalene (C12H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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

As a certified reference material (CRM), 1,4-Dihydro-5,8-dimethoxy-1,4-epoxynaphthalene 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.
