Quinine is an alkaloid isolated from Cinchona bark, used as medication to treat malaria and babesiosis.
Quinine reacts with acids forming water soluble salts.
Quinine will slowly oxidize upon exposure to air over long periods of time, in both free and salt form, turning dark.
Quinine is sold online. Often, it is sold in salt form, as sulfate.
Tonic water has small amounts of quinine, though not enough for it to be an economical source.
Quinine is best extracted from Cinchona tree bark than synthesized from precursors.
- Compound collecting
- Bitter taste mixtures
- Tonic water
- Make fluorescent drinks
- Anti-malaria drug
- Demonstration of triboluminescence
Exposure to quinine is known to cause abnormal heart rhythms.
Quinine should be kept in plastic or glass bottles, in dark places.
Can be safely poured down the drain or in trash.
