(2,4,5-trichloro-phenyl)-vinyl ether is an organochlorine compound with the chemical formula C8H5Cl3O. It is a colorless to pale yellow liquid with a pungent odor. (2,4,5-trichloro-phenyl)-vinyl ether is characterized by the presence of three chlorine atoms attached to a phenyl ring, with a vinyl ether group (-CH=CHO) attached to the 2-position of the phenyl ring. It is synthesized by reacting 2,4,5-trichlorophenol with ethylene oxide. (2,4,5-trichloro-phenyl)-vinyl ether is used as an intermediate in the production of various agrochemicals, particularly herbicides. Due to its chemical structure, it exhibits lipophilic properties, which can lead to potential environmental and health concerns, including persistence in soil and water, as well as potential bioaccumulation in organisms.
The CAS Registry Mumber 939-40-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 939-40: (5*9)+(4*3)+(3*9)+(2*4)+(1*0)=92 92 % 10 = 2 So 939-40-2 is a valid CAS Registry Number.
