β-(2,4,6-Trichlor-phenoxy-methoxy)-ethylbromid, also known as 2,4,6-trichlorophenoxymethyl ethyl bromide, is a chemical compound with the molecular formula C9H8BrCl3O3. It is a halogenated derivative of phenoxyacetic acid, characterized by the presence of three chlorine atoms at the 2, 4, and 6 positions of the phenoxy ring. β-(2.4.6-Trichlor-phenoxy-methoxy)-ethylbromid is a white crystalline solid with a molecular weight of 350.42 g/mol. It is used as a plant growth regulator and herbicide, particularly for controlling broadleaf weeds in various crops. Due to its chemical structure, it exhibits selective herbicidal activity by inhibiting the growth of unwanted plants while allowing the desired crops to grow. However, it is important to note that the use of such chemicals must be managed carefully to minimize environmental and health risks.
The CAS Registry Mumber 21112-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,1 and 2 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 21112-73: (7*2)+(6*1)+(5*1)+(4*1)+(3*2)+(2*7)+(1*3)=52 52 % 10 = 2 So 21112-73-2 is a valid CAS Registry Number.
