(3-chloro-2,4-difluoro-phenoxy)-acetic acid is a synthetic chemical compound with the molecular formula C8H5ClF2O3. It is characterized by a chlorinated phenoxy group attached to an acetic acid backbone, with two fluorine atoms substituting hydrogen atoms on the phenyl ring. (3-chloro-2,4-difluoro-phenoxy)-acetic acid is known for its herbicidal properties, particularly in controlling broadleaf and grassy weeds. It functions by inhibiting the enzyme enolpyruvylshikimate-3-phosphate synthase (EPSPS), which is crucial in the biosynthesis of aromatic amino acids in plants. The unique structure of this chemical, with its halogenated phenoxy group, contributes to its selectivity and effectiveness in weed management, making it a valuable tool in agricultural practices.
The CAS Registry Mumber 1979-23-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,7 and 9 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1979-23: (6*1)+(5*9)+(4*7)+(3*9)+(2*2)+(1*3)=113 113 % 10 = 3 So 1979-23-3 is a valid CAS Registry Number.
