2-(2,5-Dichlorphenoxy)-propionitril, also known as 2,5-dichlorophenoxypropionitrile, is a chemical compound with the molecular formula C9H6Cl2NO. It is an organic compound that features a dichloro-phenoxy group attached to a propionitrile moiety. 2-(2,5-Dichlorphenoxy)-propionitril is primarily used as an intermediate in the synthesis of herbicides, particularly in the production of 2,4-Dichlorophenoxyacetic acid (2,4-D), a widely used herbicide. The dichloro-phenoxy group is key to the herbicidal activity, as it mimics the action of plant hormones, leading to uncontrolled growth and ultimately the death of the plant. The compound is typically synthesized through a series of chemical reactions involving chlorination and substitution reactions. Due to its potential environmental and health impacts, the handling and use of 2-(2,5-dichlorphenoxy)-propionitril are subject to strict regulations to ensure safety and minimize exposure.
The CAS Registry Mumber 33695-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,9 and 5 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 33695-68: (7*3)+(6*3)+(5*6)+(4*9)+(3*5)+(2*6)+(1*8)=140 140 % 10 = 0 So 33695-68-0 is a valid CAS Registry Number.
