4-Ethyl-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol CAS 491647-36-0

Description

As a certified reference material (CRM), 4-Ethyl-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol 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.

4-Ethyl-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol (CAS 491647-36-0) is a high-purity analytical reference standard with the molecular formula C13H17N3OS and a molecular weight of 263.36 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-Ethyl-5-((4-ethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.36 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.
