Properties and stability
Colorless liquid. It is easy to burn and decompose when exposed to open flames or high heat, releasing toxic gases.
Storage method
Stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from acids and food chemicals, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.
Synthesis method
It is produced by the direct esterification of isoamyl alcohol and nitric acid in the presence of urea, but it is generally a mixture of isomers and must be separated and refined to obtain pure crystals.
Purpose
Used as solvent, pharmaceutical synthesis or chemical reagent.
