Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(4-Bromophenyl)-1-phenyl-1h-imidazole-2-thiol (CAS 1105189-61-4) is a high-purity analytical reference standard with the molecular formula C15H11BrN2S and a molecular weight of 331.23 g/mol.
5-(4-Bromophenyl)-1-phenyl-1h-imidazole-2-thiol (C15H11BrN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine 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 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), 5-(4-Bromophenyl)-1-phenyl-1h-imidazole-2-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.
