Benzo[c][1,2,5]thiadiazole-4,7-dicarbonitrile CAS 20138-79-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzo[c][1,2,5]thiadiazole-4,7-dicarbonitrile.

Benzo[c][1,2,5]thiadiazole-4,7-dicarbonitrile (CAS 20138-79-8), molecular formula C8H2N4S and molecular weight 186.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H2N4S, Benzo[c][1,2,5]thiadiazole-4,7-dicarbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
