31431-26-2 Usage

General Description

The chemical compound "(4-Amino-3-Nitrophenyl)(4-Fluorophenyl)Methanone" is a complex organic molecule that consists of two aromatic phenyl groups and a methanone group as core components. The first phenyl ring is substituted with an amino group (NH2-) and a nitro group (NO2-) at the 4th and 3rd position, respectively, which gives this part of molecule its unique properties. The second phenyl ring is substituted with a fluorine atom at the 4th position, significantly impacting its reactivity and interactions. The methanone group links these two aromatic rings, possessing a carbonyl functionality (C=O) directly attached to the phenyl rings, playing a crucial role in the structural stability of the compound. Its specific properties, including reactivity, stability, and possible applications, would depend on the precise arrangement and interactions of these functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 31431-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,3 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31431-26:
(7*3)+(6*1)+(5*4)+(4*3)+(3*1)+(2*2)+(1*6)=72
72 % 10 = 2
So 31431-26-2 is a valid CAS Registry Number.

Preparation method of flubendazole

-

, (2018/03/26)

The invention relates to a preparation method of flubendazole. The preparation method comprises the following steps: dropwise adding thionyl chloride into a reaction system taking 4-chloro-3-nitrobenzoic acid and o-dichlorobenzene as solvents, wherein DMF (Dimethyl Formamide) is used as a reaction catalyst; then dropwise adding an acylated reaction solution into a fluorobenzene and aluminum trichloride system and carrying out Friedel-Crafts reaction; adding ammonia water, methane and a Friedel-Crafts product into a closed reactor for carrying out amination reaction; adding aminate, the methaneand a palladium carbon catalyst into a high-pressure hydrogenation reactor for reducing; adding a cyclization agent into a reduced reaction solution from which a catalyst is removed for cyclizing; finally, dropwise adding hydrogen peroxide into the cyclized reaction solution for oxidizing. The preparation method disclosed by the invention has the advantages that firstly, during cyclization reaction, an intermediate has an passivation action of carbonyl, so that the cyclization reaction is smoother and reaction time is greatly shortened; secondly, nitro is reduced by adopting a hydroreductionmethod which has better economic and environment-friendly properties compared with a traditional sulfuration alkaline method; thirdly, the cyclization agent adopts lower-price methyl cyanocarbamate,so that production cost is reduced.
