English Name: ethephon; 2-Chloroethylphosphonic acid； Chlorethephon
Other names: 2-chloroethyl phosphoric acid; Ethylene phosphorus; Eisler; Zeatin; (2-chloroethyl) phosphonic acid; 2-chloroethyl phosphonic acid
CAS No.: 16672-87-0
C2H6ClO3P=144.49
Grade: ar
Content: ≥ 85.0%
Acidity (in HC1): ≤ 10%
Melting point: 74 ~ 75 ℃
Relative density: 1.258
Physicochemical Properties: white to light brown solid or liquid, easy to absorb moisture, easy to heat into liquid in summer. PH < 3, soluble in water and alcohol. It is very stable in the natural medium, and ethylene is quickly liberated in the alkaline medium. It begins to decompose when pH ＞. Toxicity: low toxicity plant growth regulator, acute oral LD50 of mice is 5110 mg / kg
Purpose: biochemical research. It is a plant growth regulator that promotes maturation and senescence. It can be absorbed by the stem, leaf, flower and fruit of the plant, and then transmitted to the cells of the plant. Generally, the pH value of cell fluid is above 4, so it is decomposed to produce ethylene, which plays the role of endogenous ethylene in plants, such as increasing the proportion of female flowers or female flower organs, promoting the flowering of some plants, dwarfing rice, corn and other crops, increasing the stem diameter, inducing the formation of adventitious roots, stimulating the germination of some plants, and accelerating the maturation, aging and shedding of leaves and fruits. However, ethylene can affect the movement of auxin and root elongation. It is a broad-spectrum plant growth regulator and has a wide range of applications in agriculture, forestry and Horticulture
