Chemical Structure
Description
3-[(trifluoromethyl)sulfanyl]-1h-1,2,4-triazol-5-amine (CAS 1154963-41-3), molecular formula C3H3F3N4S and molecular weight 184.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, 3-[(trifluoromethyl)sulfanyl]-1h-1,2,4-triazol-5-amine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 3-[(trifluoromethyl)sulfanyl]-1h-1,2,4-triazol-5-amine 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.
