Description
As a certified reference material (CRM), 5-(2-Chlorophenyl)-4-cyclopentyl-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.
5-(2-Chlorophenyl)-4-cyclopentyl-4H-1,2,4-triazole-3-thiol (CAS 750610-95-8), molecular formula C13H14ClN3S and molecular weight 279.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 5-(2-Chlorophenyl)-4-cyclopentyl-4H-1,2,4-triazole-3-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
