Properties and stability

1. Use and store according to specifications. It will not decompose and avoid contact with oxides.

2. Found in tobacco leaves.

Storage method

Packed in nitrogen-filled brown glass bottles. Store at low temperature and away from light. Be careful to prevent oxidation and deterioration.

Synthesis method

1. Plant sources include cruciferous plants, Lepidium lucidum, North American rapeseed oil, etc., which are also found in the human liver, brain, specific tissues, and animal fat. The content in human fat is small, and it is an important component of animal phospholipids. The components can be chemically synthesized.

2. Prepared from propargyloxytetrahydropyran and 1-heptyne.

Purpose

It is mainly used as a nutritional fortifier and an important raw material for the synthesis of prostaglandins. It can regulate the permeability of human cell membranes and plays an important role in the brain neurodevelopment of infants and young children. It can be used to treat or prevent coronary heart disease, diabetes and cerebrovascular diseases.
