Chemical Structure
Description
The occurrence of Diethyl 2,2'-(1,3-phenylenebis(thiazole-2,4-diyl))diacetate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl 2,2'-(1,3-phenylenebis(thiazole-2,4-diyl))diacetate (CAS 1858256-06-0), molecular formula C20H20N2O4S2 and molecular weight 416.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl 2,2'-(1,3-phenylenebis(thiazole-2,4-diyl))diacetate (C20H20N2O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Diethyl 2,2'-(1,3-phenylenebis(thiazole-2,4-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.
