Chlormequat Chloride

Common name:Chlormequat Chloride

Chemical name:Chlorination -2- Chloroethyl Trimethylamine

Chemical structural formula:

Molecular formula:C₅H₁₃Cl₂N

Molecular weight:158.07

Biological activity:Plant growth regulator

Physicochemical property:Melting point:240-241℃

Vapor pressure:(20℃) 0.010mpa

Solubility:Easily soluble in water, soluble in ethanol, slightly soluble in dichloroethane, insoluble in benzene, dimethylbenzene, ethyl ether, anhydrous ethano and acetone.

Stability:Extremely easy to air-slake when exposed to air; stable in neutral and slightly acidic solution; decompose after heating when meeting the strong alkaline substance.

Animal toxicity:Rattus norvegicus acute oral LD50 > 2,000mg/k; low toxicity.

Purpose:Chlormequat is plant growth retardants, which can inhibit plant cell to grow but will not infect cell division; it can shorten internode length and petiole of the plant and make the plants short and strong, the stalks thicken, the leaves turn green, improving insect resistance ability of plants. It can make crops endure drought and waterlog and prevent the crops from lodging; it has anti-saline ability and can prevent shedding of cotton bolls and increase the tuber of potato.

Product specification and packaging: 98% active compound, plastic bags filled with nitrogen, aluminium-foil bag, cardboard barrel, 50kg / barrel. Packaging can also be arranged according to customer requirements.

Properties

Plant growth regulator. After use, the stem can be thick, the internode shortened, the plant becomes shorter, the root system is developed, and the leaf is widened and thickened, the leaf color is dark green, and the flower, leaf and later growth will not be deformed. The ability of resistance to disease and insect can make wheat, cotton and rice resist lodging, wheat can resist salt alkali, increase tuber of potato, increase cotton, and increase cotton yield. It can be used in most grain and economic crops and vegetables, such as corn, rice, tobacco, potato and tomato, and has good yield increase effect.
