Description
As a certified reference material (CRM), Diethyl 1,4-diethoxynaphthalene-2,3-dicarboxylate 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.
Diethyl 1,4-diethoxynaphthalene-2,3-dicarboxylate (CAS 59883-08-8), molecular formula C20H24O6 and molecular weight 360.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Diethyl 1,4-diethoxynaphthalene-2,3-dicarboxylate (C20H24O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 360.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
