119-21-1 Usage
General Description
1-chloro-2,4-dimethoxy-5-nitrobenzene is a chemical compound with the molecular formula C8H8ClNO4. It is a yellow crystalline solid that is primarily used as an intermediate in the production of pharmaceuticals and agrochemicals. This chemical is also known as Monuron and is widely utilized as a herbicide to control the growth of weeds and unwanted vegetation. It works by inhibiting photosynthesis in plants, making it an effective tool for agricultural and horticultural purposes. However, due to its potential environmental and health risks, its use is regulated in many countries. As such, precautions should be taken when handling and using 1-chloro-2,4-dimethoxy-5-nitrobenzene to prevent negative impacts on the environment and human health.
Check Digit Verification of cas no
The CAS Registry Mumber 119-21-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119-21:
(5*1)+(4*1)+(3*9)+(2*2)+(1*1)=41
41 % 10 = 1
So 119-21-1 is a valid CAS Registry Number.

A simple and practical protodecarboxylation of o-nitrobenzoic acids as well as heteroaromatic carboxylic acids with various substituents via using CuI/Et3N has been established. This transformation provides a viable and low-cost approach to generating previously unavailable substituted arenes from readily accessible aryl carboxylic acids as the starting materials.
