4-[(E)-[(2,6-Dichlorophenyl)methylidene]amino]-5-(thiophen-2-yl)-4H-1,2,4-triazole-3-thiol CAS 477863-20-0

Description

As a certified reference material (CRM), 4-[(E)-[(2,6-Dichlorophenyl)methylidene]amino]-5-(thiophen-2-yl)-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-[(E)-[(2,6-Dichlorophenyl)methylidene]amino]-5-(thiophen-2-yl)-4H-1,2,4-triazole-3-thiol (CAS 477863-20-0), molecular formula C13H8Cl2N4S2 and molecular weight 355.27 g/mol, is a CATO reference standard with documented purity and traceability.

4-[(E)-[(2,6-Dichlorophenyl)methylidene]amino]-5-(thiophen-2-yl)-4H-1,2,4-triazole-3-thiol (C13H8Cl2N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
