804-63-7 - Introduction
Quinine sulfate is a colorless crystalline powder.
Nature:
Including strong solubility, easy moisture absorption, stability in air, and stability at room temperature.
Method:
The production method of quinine sulfate usually involves reacting quinine with sulfuric acid to obtain it. Firstly, emulsify and extract quinine with sodium carbonate, then add dilute phosphoric acid to produce precipitate, and finally react with concentrated sulfuric acid to obtain quinine sulfate.
Security information:
1. Try to avoid inhaling its powder and avoid direct contact with the skin and eyes to avoid irritation.
2. Attention should be paid to the use of protective measures, such as wearing gloves and goggles, and maintaining a well ventilated working environment.
3. If accidentally exposed to quinine sulfate, rinse immediately with plenty of water and seek medical attention promptly.
