4,8-Bis(7-bromo-2,3-dihydrothieno[3,4-b]-1,4-dioxin-5-yl)-2λ4δ2-benzo[1,2-c:4,5-c′]bis[1,2,5]thiadiazole CAS 1323953-37-2 chemical structure

Description

4,8-Bis(7-bromo-2,3-dihydrothieno[3,4-b]-1,4-dioxin-5-yl)-2λ4δ2-benzo[1,2-c:4,5-c′]bis[1,2,5]thiadiazole (CAS 1323953-37-2), molecular formula C18H8Br2N4O4S4 and molecular weight 632.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 4,8-Bis(7-bromo-2,3-dihydrothieno[3,4-b]-1,4-dioxin-5-yl)-2λ4δ2-benzo[1,2-c:4,5-c′]bis[1,2,5]thiadiazole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 632.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4,8-Bis(7-bromo-2,3-dihydrothieno[3,4-b]-1,4-dioxin-5-yl)-2λ4δ2-benzo[1,2-c:4,5-c′]bis[1,2,5]thiadiazole 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.
