Pyrazoles are rare in nature;-(1-pyrazolyl) alanine was isolated from the seeds of watermelon (Citrullus Lanatus)(L. Fowden) in 1959. Pyrazole compounds have a wide range of biological activities, such as anti-diabetes, anti-virus, anti-cancer, anti-inflammatory, anti-bacterial and anti-fungal activities.
Pyrazole was synthesized in one step using glycerol and Hydrazine Hydrate as dehydrogenation catalyst in sulfuric acid by using sodium iodide, which is cheap and easily obtained, and then neutralized by Liquid Alkali to Ph = 7-8, filtered to remove the inorganic salts, the mixed solution was dehydrated by benzene reflux with water, and then distilled in vacuum, the finished product is pyrazole. The overall yield was 85.6% . PYRAZOLE can also be synthesized by the reaction of,-unsaturated aldehydes with hydrazine and then dehydrogenation.
