CAS 288-13-1
Product Overview
Pyrazole (CAS 288-13-1, molecular formula C₃H₄N₂), also known as 1,2-diazole, is the parent compound featuring the pyrazole ring: a five-membered aromatic heterocycle consisting of three carbon atoms and two adjacent nitrogen atoms. This heterocyclic core complies with Hückel's rule of aromaticity and exhibits amphoteric chemical properties. It can function as both a hydrogen bond donor and acceptor, and readily coordinates with metal ions, rendering this structural skeleton extremely valuable for molecular design.
The pyrazole ring allows diverse chemical modification at different ring positions. Electrophilic substitution reactions predominantly occur at the C4 position, while functional groups can be introduced at C3 and C5 to tailor molecular characteristics. It acts as an essential building block for producing pharmaceutical intermediates, agrochemical fungicides, herbicides and insecticides. Many commercially available anti-inflammatory, analgesic and antidiabetic drugs incorporate the pyrazole ring as their key active structural unit. In the advanced materials industry, pyrazole derivatives serve as metal ligands for organometallic catalysts, MOF materials and coordination polymers.
Our pyrazole raw material is manufactured under rigorous quality management. The product exists as a white crystalline solid with high GC purity and low impurity levels. Standard packaging is a 25kg drum, and smaller laboratory trial packages are available on request. Each shipment is accompanied by COA, MSDS and other export documents to facilitate laboratory testing and customs clearance.
