43156-48-5 Usage

Uses

4-(Phenylthio)-1,2-benzenediamine is used in the synthesis of bis(2-chloroethyl)aminophosphoryl-containing compounds which are potential anticancer agents. It is also used in the synthesis of 2-substituted-2,3-dihyrdro-5-thiophenoxy-1H-1,3,2-benzodiazaphosphole 2-oxides which exhibit antimicrobial activity.

Check Digit Verification of cas no

The CAS Registry Mumber 43156-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,1,5 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 43156-48:
(7*4)+(6*3)+(5*1)+(4*5)+(3*6)+(2*4)+(1*8)=105
105 % 10 = 5
So 43156-48-5 is a valid CAS Registry Number.

Synthetic method of fenbendazole

-

, (2021/08/14)

A synthetic method of fenbendazole belongs to the technical field of insect repellents, and specifically comprises the following steps: carrying out condensation reaction on 5-chloro-2-nitroaniline and a sodium thiophenol aqueous solution in a mixed solution of n-propyl alcohol and water to obtain 5-thiophenyl-2-nitroaniline; carrying out reduction reaction on the 5-thiophenyl-2-nitroaniline in a high-pressure kettle under the catalysis of raney nickel to generate 4-thiophenyl o-phenylenediamine; and mixing the 4-thiophenyl o-phenylenediamine and N-(trichloromethyl) methyl carbamate for a cyclization reaction to obtain fenbendazole; the method has the advantages that conditions are mild, operation is easy and convenient, ammonium chloride can be prevented from being generated in the cyclization process, and the three-waste cost is low; the generation of amine salt is avoided, and the treatment cost of three wastes is greatly reduced; and the yield of the fenbendazole can reach 84.27% to 89.99%, and the purity of the fenbendazole can reach 96.39% to 99.71%.

Preparation method of 4-thiophenyl-o-phenylenediamine

-

, (2021/07/31)

The invention provides a preparation method of 4-thiophenyl-o-phenylenediamine, wherein the preparation method comprises the steps: by taking 2-nitro-4-thiocyano aniline and aniline as initial raw materials, firstly, reacting 2-nitro-4-thiocyano aniline with sodium sulfide to obtain 3-nitro-4-amino thiophenol sodium, and reacting aniline with sodium nitrite under an acidic condition to generate benzene diazonium chloride; and then condensing the benzene diazonium chloride and the 3-nitro-4-amino thiophenol sodium to obtain 2-nitro-4-thiophenyl aniline, and then carrying out a Raney nickel hydrogenation reduction reaction to obtain the 4-thiophenyl-o-phenylenediamine. The method has the characteristics of high economic benefit, low three-waste amount, low cost and the like, the total yield can reach 64.58%, and the method belongs to the technical field of organic chemical industry.

A preparation method of curing melanotumor

Paragraph 0039; 0040, (2016/10/27)

The invention discloses a preparation method of fenbendazole and provides a brand-new synthesis route of the fenbendazole. The fenbendazole is prepared from m-dichlorobenzene as a starting material through the steps of nitrification, condensation, amination, reduction and cyclization. The preparation method is characterized in that the starting material m-chloroaniline in the existing industrial route is changed to the cheap m-dichlorobenzene; the existing reduction technology with sodium sulfide dihydrate is changed to the clean and high-efficiency reduction technology; and the new synthesis technology is concise and simple, high in efficiency, slight in pollution, high in quality, and suitable to industrial production.
