Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-Ethylphenyl)-5-phenyl-1H-imidazole-4-thiol (CAS 1325305-91-6) is a high-purity analytical reference standard with the molecular formula C17H16N2S and a molecular weight of 280.39 g/mol.
The molecular framework of 2-(4-Ethylphenyl)-5-phenyl-1H-imidazole-4-thiol (C17H16N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), 2-(4-Ethylphenyl)-5-phenyl-1H-imidazole-4-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.
