2-(2,4,6-trichloro-phenoxy)-butyric acid, also known as 2,4,6-TCP or trichlorophenoxybutyric acid, is a synthetic chemical compound with the molecular formula C10H8Cl3O3. It is a derivative of phenoxybutyric acid, where the phenol group is substituted with three chlorine atoms at the 2, 4, and 6 positions. 2-(2,4,6-trichloro-phenoxy)-butyric acid has been used as a plant growth regulator and herbicide, particularly in the control of broadleaf weeds in cereal crops. However, due to its potential environmental and health risks, including endocrine disruption and persistence in the environment, its use has been restricted or banned in many countries. The chemical's properties, such as its solubility in water and its chemical structure, contribute to these concerns, making it a subject of ongoing research and regulatory scrutiny.
The CAS Registry Mumber 4641-29-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4641-29: (6*4)+(5*6)+(4*4)+(3*1)+(2*2)+(1*9)=86 86 % 10 = 6 So 4641-29-6 is a valid CAS Registry Number.
