Description
Quinine Sulfate Product Overview
Quinine sulfate dihydrate is a fine, white, needle-like crystalline powder with an intensely bitter taste. It is slightly soluble in water and darkens on exposure to light. Quinine is extracted from the bark of the cinchona tree.
Pharmaceutical companies use it in tablets for malaria in countries where it is authorized; related antimalarial APIs include Chloroquine phosphate and Hydroxychloroquine Sulfate. Beverage producers use small amounts of quinine as the characteristic bitter flavor of tonic water and bitter lemon, within maximum limits set by food regulations.
In laboratories, quinine sulfate dissolved in dilute sulfuric acid is a classic standard for calibrating fluorescence measurements. Zyntex supplies pharmaceutical and food-grade material with appropriate documentation.
