Properties and stability

Avoid contact with strong oxidants and water.

Storage method

Stored in a cool, ventilated warehouse. Keep away from fire, heat and water 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. The “five pairs” management system for extremely toxic substances should be strictly implemented.

Synthesis method

Prepared by nickel-catalyzed hydrogenation of 1-methyl-4-piperidone.

Purpose

Intermediates of phenthiidine and cyproheptadine hydrochloride.
