Description:(2R,3S,22S,24S)-2,3,22,23-tetrahydroxy-24-ethyl-beta-homo-7-oxa-5a-cholestan-6-one is a white crystalline powder with effective composition of >95%, m.p.256 ~ 258℃, soluble in methanol, ethanol, tetrahydrofuran, acetone and other organic solvents, with a solubility of 5mg/L in water.
(2R,3S,22S,24S)-2,3,22,23-tetrahydroxy-24-ethyl-beta-homo-7-oxa-5a-cholestan-6-one belongs to sterol plant hormones. At very low concentrations it significantly increases plant nutrient growth and promotes fertilization. Its high physiological activity can be shown at a concentration of 0.1 ~ 0.001mg/L. Its main function is to improve fruit setting rate, promote crop growth, improve seed setting rate, increase 1000-grain weight and improve crop cold resistance, disease resistance, reduce drug damage. The concentration of 0.05-0.5mg /L was used to soak the wheat for 24h, promote the root system (including root length and number) and plant height, and increase the number of tillers. In the booting stage of wheat, the concentration of 0.01-0.05mg /L was used to spray the leaves, and the effect of increasing yield was particularly obvious. The total analysis spray treatment with 0.01mg/L concentration of maize can significantly reduce the abortive rate of corn on the top of ear and increase the yield by about 20%. Especially, the effect before tasseling is better than that after spinning.
Appearance:White crystallized powder
Use:It is a broad-spectrum high-efficient plant growth substance
