Properties and stability

1. Stable at room temperature and pressure, avoid contact with strong oxidants and light.

2.Reacts with a variety of inorganic ions to produce colored substances.

Storage method

1. Store in a cool, ventilated warehouse. Keep away from light. Keep away from fire and water sources.

2. They should be stored separately from oxidants and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment.

3. The storage area should be equipped with suitable materials to contain leaks.

Synthesis method

1. Plant sources include the bark of the Rubiaceae plant red cinchona tree, the bark of cinchona, etc. It can also be biosynthesized into hydrochloride and tartrate. It has anti-plasmodial and antipyretic effects.

2. Cinchona bark can be extracted to obtain alkaloids. The crude product is dissolved with nitric acid and then precipitated with ammonia water. The resulting white precipitate is cinchonine. .


1. Used for the determination of molybdenum and tungsten, photometric determination of bismuth, and verification of bismuth, antimony, germanium, cadmium, molybdenum and tungsten. Resolution of racemic organic acids.

2.Used for thin layer chromatography determination of bismuth, silver, mercury, lead, Reagents for antimony, vanadium, copper, and platinum ions. It is also used as an indicator for precipitation titration determination of iodide.
