Properties and stability
Avoid contact with strong acids, alkalis, and strong oxidants.
Storage method
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from oxidants, acids, and alkalis, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.
Synthesis method
It is obtained by esterification, condensation, chlorination and reaction using butynediol, m-chloroaniline, phosgene and thionyl chloride as raw materials.
Purpose
Used as a herbicide, mainly for post-emergence control of wild oats.
