| Introduction | benzenylurea [1-(2-chloropyridin-4-yl)-3-phenylurea,CPPU], also known as benzenylurea, KT-30, etc, it is a kind of plant growth regulator of cytokinin, which can induce the growth of callus and promote the development of Bud before harvest, it has a significant effect on the control of postharvest leaves yellowing and postharvest diseases of various fruits and vegetables. For example, CPPU has a significant effect on delaying the yellowing of cabbage and rice leaves. |
| toxicity | Acute Oral LD501510mg/kg in mice and acute percutaneous LD50>10000mg/kg in rats. Mild irritation to rabbit skin. Ames test and micronucleus test showed no mutagenic effect. |
| Use | urea is a phenylurea cytokinin, which can affect the development of plant buds, accelerate cell mitosis, promote cell proliferation and differentiation, prevent the role of fruit and flower shedding, thereby promoting plant growth, early maturity, delay the senescence of the leaves of crops, increase yield. The main manifestations are as follows: ① the function of promoting the growth of stem, leaf, root and fruit, such as tobacco planting can make the leaf hypertrophy and increase the yield. (2) to promote the results. Can increase the yield of tomatoes (tomatoes), eggplant, apples and other fruits and vegetables. ③ accelerating fruit thinning and defoliation. Fruit thinning can increase fruit yield, improve fruit quality and make fruit size uniform. For cotton and soybean, defoliation can make harvesting easy. The high concentration can be used as herbicides. (5) others. Such as the role of dry cotton, sugar beet and sugar cane increased sugar. used as plant growth regulator, with cytokinin activity, can promote cell division, differentiation, organ formation, protein synthesis, improving photosynthesis, etc. is a kind of phenylurea plant growth regulator with cytokinin activity, but its biological activity is 10-100 times higher than that of 6-benzylaminopurine. Widely used in agriculture, horticulture and fruit trees, promote cell division, promote cell expansion and elongation, promote fruit hypertrophy; Improve yield; Preservation and so on. |
| production method | preparation method-preparation of 2-chloro-4-aminopyridine 2-chloropyridine is used as raw material, in acetic acid medium, with hydrogen peroxide as oxidant, oxidation to 2-chloropyridine-N-oxide, nitration of 2-chloro-4-nitropyridine-N-oxide with mixed acid, the reduction is then carried out in a conventional manner to give 2-chloro-4-aminopyridine. Isonicotinic acid can also be used as a raw material, and Isonicotinic acid N-oxide can be generated by oxidation with hydrogen peroxide, and isonicotinamide N-oxide can be obtained by amination, followed by chlorination to generate 2-chloro-isonicotinamide, finally, 2-chloro-4-aminopyridine was produced by the Hofmann degradation reaction. Preparation of phenyl isocyanate Aniline reacts with phosgene to produce phenyl isocyanate. Synthesis of chlorourea 2-chloro-4-aminopyridine was reacted with phenyl isocyanate to form chlorourea. Method of preparation di-2-chloro-4-pyridyl isocyanate is reacted with aniline to prepare formazan. Preparation Method tri-2-chloroisonicotinoyl chloride is reacted with sodium azide to produce a 2-chloroisonicotinoyl azide compound, which is then reacted with aniline in a drying vessel to produce a flourea. |
