General Description
N-(4-Chloro-3-methylphenyl)-3-amino-4-chlorobenzamide, also known as Diuron, is a chemical compound commonly used as an herbicide to control the growth of weeds in various agricultural and industrial settings. It belongs to the class of substituted urea compounds and works by inhibiting photosynthesis in plants, leading to their eventual death. Diuron is a white crystalline solid with a slightly aromatic odor and is sparingly soluble in water. It is considered to have a moderate toxicity level and can cause skin and eye irritation, as well as potential health risks if ingested or inhaled in high quantities. Due to its potential impact on environmental and human health, the use of Diuron is regulated in many countries.
Check Digit Verification of cas no
The CAS Registry Mumber 59158-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,5 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 59158-04:
(7*5)+(6*9)+(5*1)+(4*5)+(3*8)+(2*0)+(1*4)=142
142 % 10 = 2
So 59158-04-2 is a valid CAS Registry Number.

Synthesis method of 3-amino-4-chloro-N-(3-chloro-2-methylphenyl)benzamide
-
Paragraph 0005; 0014; 0015, (2016/12/22)
The invention discloses a synthesis method of 3-amino-5-chloro-N,3-dimethyl benzamide, and belongs to the organic chemical synthesis technical field. The synthesis method comprises the steps: 3-nitro-4-chlorobenzoic acid is used as a raw material, N,N'-diisopropyl carbodiimide is used as a condensing agent, 1-hydroxybenzotriazole is used as a condensation activator, firstly, 3-nitro-4-chlorobenzoic acid and N,N'-diisopropyl carbodiimide are subjected to an addition reaction, an addition product is not stable and is converted to a corresponding ester under the action of 1-hydroxybenzotriazole, then the corresponding ester is subjected to a reaction with 3-chloro-2-methylaniline to obtain 3-nitro-4-chloro-N-(3-chloro-2-methylphenyl)benzamide, next the 3-nitro-4-chloro-N-(3-chloro-2-methylphenyl)benzamide is reduced into 3-amino-4-chloro-N-(3-chloro-2-methylphenyl)benzamide under the action of zinc and sodium hydroxide. The synthesis method has the advantages of simple operation, less steps, and short production cycle, and the synthesis yield is increased significantly and is increased to 95% or more.
