4-Ethyl-5-(2-phenylquinolin-4-yl)-4h-1,2,4-triazole-3-thiol CAS 588673-84-1

Description

As a certified reference material (CRM), 4-Ethyl-5-(2-phenylquinolin-4-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-Ethyl-5-(2-phenylquinolin-4-yl)-4h-1,2,4-triazole-3-thiol (CAS 588673-84-1), molecular formula C19H16N4S and molecular weight 332.42 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Ethyl-5-(2-phenylquinolin-4-yl)-4h-1,2,4-triazole-3-thiol (C19H16N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 332.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
