Description

Quinine is a naturally occurring alkaloid, historically renowned as the primary treatment for malaria. Its significance extends beyond pharmaceuticals due to its distinct bitter flavor profile and fluorescence properties. This versatile compound is essential for manufacturers in the pharmaceutical, food and beverage, and analytical reagent industries seeking a reliable, high-purity ingredient.

Application

• Pharmaceutical Active Ingredient: Key component in anti-malarial medications and used in some formulations for nocturnal leg cramps.
• Bittering Agent: Imparts the characteristic bitter taste in tonic waters, bitter liqueurs, and other specialty beverages.
• Analytical Chemistry: Used as a fluorescent standard and chiral selector in various chromatographic and spectroscopic methods.
• Food Flavoring: Employed as a flavor adjunct (FEMA 2977) in certain food products where a bitter note is desired.
• Chemical Synthesis: Serves as a chiral starting material or catalyst in the synthesis of more complex organic molecules.
