1,2,3-1H-Triazole Usage And Synthesis

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
