Chemical Structure
Description
The molecular framework of 4-Allyl-5-(2-bromophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (C11H10BrN3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-Allyl-5-(2-bromophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 328090-49-9) is a high-purity analytical reference standard with the molecular formula C11H10BrN3S and a molecular weight of 296.19 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
