It is a white crystalline solid that is soluble in water and various organic solvents. 2',4',-Dichlor-6'-hydroxybutyrophenon is primarily used as a chemical intermediate in the synthesis of herbicides, such as 2,4-dichlorophenoxyacetic acid (2,4-D), which is a widely used selective herbicide for controlling broadleaf weeds in agricultural settings. Due to its potential environmental and health impacts, the production and use of 2,4-dichlorophenol are subject to strict regulations in many countries. It is also important to note that 2,4-dichlorophenol can be toxic and has been classified as a hazardous substance, necessitating proper handling and disposal to minimize risks to human health and the environment.
The CAS Registry Mumber 1133-34-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 3 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1133-34: (6*1)+(5*1)+(4*3)+(3*3)+(2*3)+(1*4)=42 42 % 10 = 2 So 1133-34-2 is a valid CAS Registry Number.
