General Description
1,5-Dichloro-3-methyl-2-nitrobenzene is a chemical compound with the molecular formula C7H5Cl2NO2. It is a yellow crystalline solid that is commonly used as an intermediate in the production of dyes, pigments, and pharmaceuticals. 1,5-DICHLORO-3-METHYL-2-NITROBENZENE is classified as a nitrobenzene derivative and contains two chlorine atoms, one methyl group, and one nitro group attached to a benzene ring. It is known to be toxic and may cause irritation to the skin, eyes, and respiratory system upon exposure. Additionally, it is considered harmful to aquatic organisms and can have long-lasting effects on the environment if not properly handled and disposed of.
Check Digit Verification of cas no
The CAS Registry Mumber 118665-00-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,6 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118665-00:
(8*1)+(7*1)+(6*8)+(5*6)+(4*6)+(3*5)+(2*0)+(1*0)=132
132 % 10 = 2
So 118665-00-2 is a valid CAS Registry Number.

Sheet 0045-0046; 0054; 0065, (2021/01/28)
The invention belongs to the technical field of preparation of pesticide intermediates, and particularly discloses a preparation method of a dichlorotoluene nitride intermediate. The preparation method comprises the following steps: fully reacting raw materials, a solvent and a nitration reagent to obtain a dichlorotoluene nitride intermediate, wherein the raw materials comprise any one of o-dichlorotoluene, m-dichlorotoluene and p-dichlorotoluene; the solvent is dichloroethane; the nitration reagent is concentrated nitric acid; the dichlorotoluene nitride intermediate is shown as a chemical formula 7 and a chemical formula 12. The preparation method has the advantages that the corrosion to reaction equipment is less, and the generation and discharge of waste acid and waste salt in the production process are greatly reduced.
