Description

Compared with other compounds in its class, the molecular weight of 296.19 g/mol gives 5-(4-Bromophenyl)-4-cyclopropyl-4H-1,2,4-triazole-3-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(4-Bromophenyl)-4-cyclopropyl-4H-1,2,4-triazole-3-thiol (CAS 919970-09-5) is a high-purity analytical reference standard with the molecular formula C11H10BrN3S and a molecular weight of 296.19 g/mol.

5-(4-Bromophenyl)-4-cyclopropyl-4H-1,2,4-triazole-3-thiol (C11H10BrN3S) 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 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.

As a certified reference material (CRM), 5-(4-Bromophenyl)-4-cyclopropyl-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.
