Description
3878AE 4-Propyl-5-thien-2-yl-4H-1,2,4-triazole-3-thiol 451501-84-1 C9H11N3S2 (CAS 451501-84-1) is a high-purity analytical reference standard with the molecular formula C9H11N3S2 and a molecular weight of 225.33 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3878AE 4-Propyl-5-thien-2-yl-4H-1,2,4-triazole-3-thiol 451501-84-1 C9H11N3S2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.33 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.
