Usage

General Description

1,5-Dimethylpyrazole is a chemical compound with the molecular formula C5H8N2. It is a pyrazole derivative and is commonly used as a building block in organic synthesis. This chemical is a colorless liquid with a slightly sweet odor, and it is soluble in water and most organic solvents. 1,5-Dimethylpyrazole is widely used as a corrosion inhibitor for copper and copper alloys, as well as in the production of pharmaceuticals and agricultural chemicals. It is also used in the synthesis of polymers and coordination compounds. However, it is important to handle this chemical with care as it is flammable and may cause irritation to the skin and eyes upon contact.
