1. important pharmaceutical raw material
cyanamide is mainly used for the production of hydrochloric acid cytarabine, dye intermediate 3-amino-5-hydroxy-1,2,4-nitrogen azole, cyanide urea amine, melamine methyl carbamate, cyanide urine amide, thiourea, carbendazim. it is also raw material for preparation of organic guanidine, then the product pharmaceutical barbituric acid, sulfa drugs and guanidine salt, etc. it can also be used for production anticancer drugs of fluorouracil in medicine. cyanamide calcium salt can be used for clinical treatment of alcoholism and anthelmintic action.
2. raw materials for chemical pesticides
2.1 cyanamide can be used as chemical raw materials of no residue, low toxicity, broad-spectrum pesticide, and can also be used for production of antibacterial agent such as carbendazim, benzene benomyl, methyl mepanipyrim and mepanipyrim, pirimicarb, pyrimidinoxy phosphorus, herbicide chlorsulfuron, metsulfuron methyl, metsulfuron methyl ethyl, long ether tribenuron methyl and bensulfuron methyl and pyrazole ethyl, hexazinone, etc. it has the significance of technological innovation for pesticide production, solves the environmental pollution while the general pesticide production enterprises can be difficult to solve the problem using calcium cyanamide in the production of pesticide. so using cyanamide can save equipment investment, reduce production costs.
2.2 in recent years, cyanamide is used as off leaf agents, herbicides and pesticides in abroad, but also can be used as pesticide, and cyanamide has a certain of nitrogen application effect. cyanamide solution was used as a defoliant, non-toxic pesticides for fruit trees in abroad.
2.3 the cyanamide in agriculture can be used as plant growth regulators, with both pesticidal and bactericidal effects. directly sprayed on crops, can effectively inhibit the activity of catalase in plants, accelerate plant oxidative pentose phosphate (ppp) circulation, thus speeding up the generation of basic substances in plants, play a role in the regulation of growth. the field efficacy trials showed that it can regulate the growth and increase production of cherries and grapes. before 15 to 20 days in grape germination, it sprayed evenly on the branches, uniform of a drug on bud eye, can advance germination of 7 to 10 days. for early flowering, full flowering stage, coloring period and mature period, using it can aslo advance early. at the same time it is good dormancy terminating agent in the production of kiwi, cherries, grapes. it sprayed evenly on bud eye in the dormant period, it can break the dormancy period, can be early germination, early flowering, early mature and early on the market. it can significantly improve the yield, change fruit fleshy and improve the quality of varieties.
