Chemical Structure

4-Amino-2,1,3-benzothiadiazole CAS 767-64-6 chemical structure

Description

As a certified reference material (CRM), 4-Amino-2,1,3-benzothiadiazole 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.

CATO supplies 4-Amino-2,1,3-benzothiadiazole (CAS 767-64-6), a certified reference material (molecular formula C6H5N3S, MW 151.19 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 4-Amino-2,1,3-benzothiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
