Nicotine pure refers to a highly concentrated and unadulterated form of nicotine, typically extracted from the leaves of the tobacco plant. It is a colorless to pale yellow liquid with a characteristic odor, and it is known for its highly addictive properties. Nicotine pure is used in various industries, including pharmaceuticals, where it serves as an active ingredient in smoking cessation products and nicotine replacement therapies. It is also utilized in the agricultural sector as an ingredient in certain pesticides. However, due to its high toxicity, handling nicotine pure requires strict safety precautions to prevent accidental exposure or ingestion.
