product description

Quinine(130-95-0), an alkaloid derived from the bark of the cinchona tree, is a blood schizontocidal agent that is more toxic than chloroquine. Quinine is used to treat malaria caused by Plasmodium falciparum. Plasmodium falciparum is a parasite that gets into the red blood cells in the body and causes malaria. Quinine works by killing the parasite or preventing it from growing. This medicine may be used alone or given together with one or more medicines for malaria.

Product Usage

Quinine, a natural alkaloid historically derived from cinchona bark, is a multifunctional compound with significant applications in medicine and the food industry. Its most critical role remains in the pharmaceutical sector, where it is a vital anti-malarial medication used to treat severe Plasmodium falciparum infections and as an ingredient in treatments for nocturnal leg cramps. In the food and beverage industry, Quinine is the signature bittering agent in tonic water and various bitter lemons, providing the quintessential flavor profile for classic cocktails. Beyond consumption, it is utilized in analytical chemistry as a standard fluorescence reference due to its highly predictable quantum yield under UV light. Additionally, its unique chemical properties allow it to serve as a chiral resolving agent in asymmetric organic synthesis, assisting in the production of pure enantiomers for advanced drug manufacturing.
