Introduction
5-Methylfurfural, also known as 5-methyl-2-oxocyclopenten-1-aldehyde or 3-methyl-4-oxoamyl acetate. The following is an introduction to the properties, uses, preparation methods and safety information of 5-methylfurfural:
Quality:
Appearance: 5-Methylfurfural is a colorless liquid with a special aroma.
Density: approx. 0.94 g/mL.
Solubility: Can be dissolved in water, alcohols and ether solvents.
Use:
Chemical synthesis intermediate: It can also be used in the synthesis of other organic compounds and as a synthetic precursor for hydroquinone.
Method:
A common synthetic route is through a catalytic reaction of Bacillus isosparatus-related enzymes. Specifically, 5-methylfurfural can be obtained by strain fermentation of butyl acetate.
Safety Information:
5-Methylfurfural is irritating to the skin and eyes, so you must pay attention to protect your hands and eyes and avoid contact during use.
Inhalation of high concentrations of 5-methylfurfural may cause uncomfortable symptoms such as dizziness and drowsiness, so ensure that it is used in a well-ventilated area and avoid prolonged exposure to high concentrations of vapor.
When storing and handling 5-methylfurfural, care should be taken to avoid contact with the oxidant to prevent fire or explosion. Make sure the storage container is well sealed and stored in a cool, dry and ventilated place, away from fire.
