Chemical Structure

5-Amino-4-phenyl-1,2,3-thiadiazole CAS 78301-72-1 chemical structure

Description

CATO manufactures 5-Amino-4-phenyl-1,2,3-thiadiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

5-Amino-4-phenyl-1,2,3-thiadiazole (CAS 78301-72-1) is a high-purity analytical reference standard with the molecular formula C8H7N3S and a molecular weight of 177.23 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-Amino-4-phenyl-1,2,3-thiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.23 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.
