(2,4-dibromo-phenoxy)-acetic acid methyl ester, also known as 2,4-dibromophenoxyacetic acid methyl ester or DBP-MEA, is an organobromine compound with the chemical formula C9H8Br2O3. It is a white crystalline solid that is soluble in organic solvents. (2,4-dibromo-phenoxy)-acetic acid methyl ester is primarily used as a plant growth regulator and herbicide, particularly in the control of broadleaf weeds and grasses in various crops. It works by mimicking the action of auxins, which are natural plant hormones, leading to uncontrolled growth and eventually plant death. Due to its potential environmental and health risks, its use has been restricted or banned in some countries.
The CAS Registry Mumber 2867-52-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 7 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2867-52: (6*2)+(5*8)+(4*6)+(3*7)+(2*5)+(1*2)=109 109 % 10 = 9 So 2867-52-9 is a valid CAS Registry Number.
