5,6-Dinitro-4,7-bis(6-undecylselenopheno[3,2-b]thiophen-2-yl)benzo[c][1,2,5]thiadiazole CAS 2607087-90-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,6-Dinitro-4,7-bis(6-undecylselenopheno[3,2-b]thiophen-2-yl)benzo[c][1,2,5]thiadiazole.

5,6-Dinitro-4,7-bis(6-undecylselenopheno[3,2-b]thiophen-2-yl)benzo[c][1,2,5]thiadiazole (CAS 2607087-90-9), molecular formula C40H50N4O4S3Se2 and molecular weight 904.96 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5,6-Dinitro-4,7-bis(6-undecylselenopheno[3,2-b]thiophen-2-yl)benzo[c][1,2,5]thiadiazole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 904.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
