Properties and stability

Low melting point white crystal, which can become colorless to light yellow liquid under supercooling. Has a floral aroma and sweet vanilla flavor. Soluble in most non-volatile oils, mineral oil and propylene glycol, insoluble in glycerin and water.

Storage method

Store in a cool and dark place.

Synthesis method

It is obtained by the addition reaction of acetone and benzyl magnesium chloride or benzyl magnesium bromide, followed by hydrolysis and distillation under reduced pressure.

Purpose

Prepare floral fragrances, such as lily, narcissus, jasmine, lily of the valley and other high-end floral fragrances. Its acetate has a refreshing aroma, making it particularly valuable. It is commonly used in floral fragrances such as hyacinth, lily, and jasmine.
