Storage method
Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The storage temperature should not exceed 37℃. The package should be sealed and not in contact with air. It should be stored separately from oxidizers and acids, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable containment materials.

Main use
1. It can be used as a soil fumigant with chlorophenic mixture, and also as a chemical reagent and solvent to treat soil before crop planting, and can prevent and control nematodes such as root-knot nematodes, brachysoma nematodes, cytosac nematodes and underground pests of various crops.
2. Used for organic synthesis and as a mildew prevention agent. It can also be used as a pharmaceutical intermediate.
