Chemical Structure

Benzo[c][1,2,5]thiadiazole-4-carboxamide CAS 1823869-65-3 chemical structure

Description

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.

Benzo[c][1,2,5]thiadiazole-4-carboxamide (CAS 1823869-65-3), molecular formula C7H5N3OS and molecular weight 179.20 g/mol, is a CATO reference standard with documented purity and traceability.

Benzo[c][1,2,5]thiadiazole-4-carboxamide (C7H5N3OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
