Chemical Structure
Description
3465AE 436089-85-9 5-[2-(1H-Benzoimidazol-2-yl)-ethyl]-4-methyl-4H-[1,2,4]triazole-3-thiol C12H13N5S (CAS 436089-85-9) is a high-purity analytical reference standard with the molecular formula C12H13N5S and a molecular weight of 259.33 g/mol.
The molecular framework of 3465AE 436089-85-9 5-[2-(1H-Benzoimidazol-2-yl)-ethyl]-4-methyl-4H-[1,2,4]triazole-3-thiol C12H13N5S (C12H13N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
