Properties and stability

1. Found in flue-cured tobacco leaves, burley tobacco leaves, and oriental tobacco leaves.

Storage method

This product should be sealed and stored in a cool, dry place.

Synthesis method

1. It is rich in soybeans, as well as others such as lentils, cocoa butter, rapeseed oil, etc. It is generally not absorbed and utilized by animals. The unsaponifiable matter in soybean oil is acetylated and brominated, and then the insoluble tetrabromide is separated and extracted using a mixed solvent of ether and acetic acid, and the insoluble tetrabromide is debrominated and saponified with zinc and acetic acid to prepare it.

2. Tobacco: FC, 8, 14, 32, 41, 43; BU, 9; BU, OR, 14.

3. Obtain crystals from ethanol-water.

Purpose

Used as raw material for steroid hormone synthesis.
