Urea, N-(3,4-dichlorophenyl)-N'-2-pyridinyl-, also known as Diuron, is a widely used herbicide belonging to the chemical class of substituted urea compounds. It is characterized by its ability to inhibit photosynthesis in plants, specifically by blocking the photosystem II reaction in chloroplasts. Diuron is effective against a broad spectrum of weeds, making it a popular choice for agricultural and non-agricultural applications. It is used to control the growth of unwanted vegetation in various settings, including crop fields, lawns, and industrial areas. The chemical structure of Diuron features a urea group linked to a 3,4-dichlorophenyl ring and a 2-pyridinyl ring, which contributes to its herbicidal activity. Due to its persistence in the environment and potential for leaching into water systems, there has been increased scrutiny and regulation of Diuron's use in recent years to minimize ecological impacts.

13142-49-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13142-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13142-49:
(7*1)+(6*3)+(5*1)+(4*4)+(3*2)+(2*4)+(1*9)=69
69 % 10 = 9
So 13142-49-9 is a valid CAS Registry Number.

A Cu-Promoted C-N Coupling of Boron Esters and Diaziridinone: An Approach to Aryl Ureas

Li, Jing,Wang, Xiaoyu,Wang, Zhanwei,Shi, Yian

, p. 8958 - 8962 (2021/11/24)

A novel Cu-promoted C-N coupling between boron esters and di-tert-butyldiaziridinone is described. A wide variety of aryl ureas can be readily obtained under mild conditions with up to a 92% yield.

Metal-free synthesis of pyridin-2-yl ureas from 2-aminopyridinium salts

Saroj,Patel, Om P.S.,Rangan, Krishnan,Kumar, Anil

, (2019/07/23)

An unprecedented base promoted domino approach has been developed for the synthesis of pyridin-2-yl urea derivatives via the reaction of 2-aminopyridinium salts and arylamines. The developed strategy tolerated a wide range of functional groups and afforded pyridin-2-yl ureas in moderate to good yields. The reaction was postulated to involve tandem cyclization, intermolecular nucleophilic addition, ring opening, and demethylation.
