Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.18 g/mol gives 2-(1H-1,2,4-Triazol-1-yl)thiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(1H-1,2,4-Triazol-1-yl)thiazole (CAS 856862-18-5) is a high-purity analytical reference standard with the molecular formula C5H4N4S and a molecular weight of 152.18 g/mol.
The molecular framework of 2-(1H-1,2,4-Triazol-1-yl)thiazole (C5H4N4S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(1H-1,2,4-Triazol-1-yl)thiazole 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.
