1,2,3-1H-Triazole Chemical Properties,Usage,Production
Description
1,2,3-1H-Triazole is a kind of azole compound. It can effectively promote the proton conduction in polymer electrolyte membranes via an intermolecular proton-transfer mechanism. It is also a useful triazole for proteomics research1. It also find use in research as a bioisostere in medicinal chemistry as well as an building block for more complex chemical compounds, including pharmaceutical drugs such as mubritinib and tazobactam2. It is a main class of hetero-cycles because of its extensive range of biological properties such as antimicrobial, anticancer, anti-tubercular, anti-HIV, antimalarial, antibacterial, antifungal, antiviral and anti-diabetic property3.
Chemical Properties
clear colorless liquid
Uses
A basic 5-membered aromatic heterocycle used as a building block for more complex pharmaceutical compounds. There have been recent studies that showed antitumor, antiinflammatory, analgesic, antifunga l, antibacterial and antiviral activities in bioactive triazoles.
Uses
It effectively promotes the proton conduction in polymer electrolyte membranes via an intermolecular proton-transfer mechanism. A useful triazole for proteomics research

General Description
2H-1,2,3-triazole is tautomeric form of 1H-1,2,3-triazole. 1H-1,2,3-triazole effectively promotes the proton conduction in polymer electrolyte membranes via an intermolecular proton-transfer mechanism.
Synthesis

288-36-8
General procedure for the synthesis of 1,2,3-triazole from 1H-1,2,3-triazole-4,5-dicarboxylic acid: to a 2000 mL four-neck flask was added 1250 mL of pure water and 157.08 g (1.0 mol) of 1H-1,2,3-triazole-4,5-dicarboxylic acid, followed by the addition of 4.71 g (equivalent to 1H-1,2,3-triazole-4,5-dicarboxylic acid 3% by mass) of N,N-diisopropylethylamine. The reaction mixture was heated to 100~110°C under atmospheric pressure and refluxed until the reaction solution was clarified. Refluxing was continued for 1 h. The reaction was monitored by HPLC and terminated when the residue of 1H-1,2,3-triazole-4,5-dicarboxylic acid was less than 1%. After completion of the reaction, filtration was performed. A vacuum pump was used to remove most of the water from the filtrate, which was then replaced with a mechanical pump for high vacuum dehydration. The four-necked flask was mounted on a distillation apparatus and vacuum distillation was carried out, resulting in 66.48 g of 1H-1,2,3-triazole with a molar yield of 96.25% and a GC purity of 99.56%.
