Properties and stability

Avoid contact with strong oxidizing agents.

Colorless liquid. It has a strong grassy and sweet aroma. More stable than phenylacetaldehyde. Soluble in ethanol, most non-volatile oils and propylene glycol, insoluble in water, glycerin and mineral oil.
The natural product is found in cocoa beans.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging is sealed. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.

Synthesis method

Synthesized from phenylacetaldehyde and methanol under the catalysis of acid or cation exchange resin.

Purpose

It is suitable for floral flavors such as rose, lilac, hyacinth and jasmine, as well as edible flavors such as plums and apricots.
