Pharmaceutical Intermediates

P-bromotrifluoromethyltoluene and p-trifluoromethylphenol are important pharmaceutical and pesticide intermediates, which can be widely used in the synthesis of a variety of new anticancer drugs, as well as pesticides and herbicides.

1-bromo-4 - (Trifluoromethoxy) benzene is an intermediate of plant growth regulator furazol.

This product is mainly used as an intermediate in the synthesis of medicine or pesticide, and can be used in the synthesis of doxazosin. Doxazosin is a α 1 selectivity α A blocker that inhibits norepinephrine from interacting with the membrane of vascular smooth muscle cells α- 1 receptor binding. The main effect of this inhibition is to relax the tension of vascular smooth muscle (vasodilation), which reduces peripheral vascular resistance and leads to lower blood pressure. * it is used clinically to treat hypertension and urinary retention associated with benign prostatic hyperplasia.

2,3,4,6-tetrabenzyl-d-glucopyranose is an important D-glucopyranose derivative, which is used as a pharmaceutical intermediate, biochemical reaction and other reactions.

Cyanamide is mainly used for the production of cytidine hydrochloride, dye intermediate 3-amino-5-hydroxy-1,2,4-triazole, cyanuronamide, cyanamide, cyanamide, cyanamide, cyanurimide, thiourea, carbendazim, etc; It is also the raw material for the preparation of organic guanidine, and then produces barbituric acid, sulfonamide medicine, guanidine salt, etc; In medicine, it can also be used to produce fluorouracil, an anti-cancer drug; Cyanamide calcium salt is used in alcohol poisoning and has the effect of insect repellency. Cyanamide can be used as raw materials for chemical pesticides without residue, low toxicity and broad-spectrum, and also can be used to produce fungicides such as carbendazim, Benazolin, methylazoxyamine, azoxyamine, insecticide against aphimethacin, pyrimidinol, herbicides such as Chlorsulfuron, methasulfuron, methasulfuron, ether benzenesulfuron, benzyl Sulfuron, pyrazosulfuron and cyclozine. It is of great significance to the technical innovation of pesticide production, which can solve the environmental pollution problems that are difficult to solve when the general pesticide manufacturers buy lime nitrogen to produce pesticides, turn to buy cyanamide to produce pesticides, save equipment investment and reduce production cost. In addition, cyanamide can also be used to produce o-methyl-isourea, creatine, guanidine phosphate flame retardant, etc. at the same time, as a flame retardant with excellent performance, monocyanamide polyol or polyether solution can be used to produce polyurethane, which can obviously improve the flame retardant performance of polyurethane materials, and is a new fine chemical new material.
