Pure Nicotine USP/EP 99+ refers to nicotine products that meet the standards set by the United States Pharmacopeia (USP) or the European Pharmacopoeia (EP) with a purity level of 99% or higher. These high-quality nicotine products are commonly used in pharmaceuticals, nicotine replacement therapies, agriculture, and vaping. Companies like Nicotine India, Alchem International, and Inovogen Life Sciences offer pure nicotine products that meet these stringent standards. It's essential to verify the credentials and reputation of the suppliers to ensure product quality and adherence to safety standards. Additionally, follow all safety guidelines for handling and using pure nicotine products, as they can be potent substances.
