2-Methoxy-6-methyl-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl diacetate CAS 142348-01-4 chemical structure

Description

The occurrence of 2-Methoxy-6-methyl-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl diacetate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Methoxy-6-methyl-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl diacetate (CAS 142348-01-4), molecular formula C20H16O7 and molecular weight 368.34 g/mol, is a CATO reference standard with documented purity and traceability.

2-Methoxy-6-methyl-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl diacetate (C20H16O7) contains a flavonoid core, a hydroxyl group, an ether linkage. 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), 2-Methoxy-6-methyl-9,10-dioxo-9,10-dihydroanthracene-1,5-diyl diacetate 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.
