Ethyl 2-(2,4-dichlorophenoxy)-2,2-difluoroacetate is a chemical compound with the molecular formula C6H5Cl2F2O3. It is an organofluorine compound that belongs to the class of phenoxyacetate herbicides. ethyl 2-(2,4-dichlorophenoxy)-2,2-difluoroacetate is known for its herbicidal properties, particularly in controlling broadleaf and grassy weeds in various agricultural settings. It works by inhibiting the enzyme enolpyruvylshikimate-3-phosphate synthase (EPSPS), which is crucial in the biosynthesis of aromatic amino acids in plants, thus disrupting their growth. The chemical structure features a difluoroacetic acid moiety linked to a 2,4-dichlorophenoxy group, which contributes to its selective herbicidal activity. Due to its potential environmental and health impacts, the use of this chemical is subject to regulatory controls to ensure its safe application and minimize risks.

889-02-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 889-02-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 889-02:
(5*8)+(4*8)+(3*9)+(2*0)+(1*2)=101
101 % 10 = 1
So 889-02-1 is a valid CAS Registry Number.

XeF2 is demonstrated to be a more proficient fluorine-transfer reagent than either NFSI or Selectfluor in fluorodecarboxylations of both mono- and difluoroaryloxy acetic acid derivatives. This method efficiently converts a wide range of neutral and electron-poor substrates to afford the desired di- and trifluoromethyl aryl ethers in good to excellent yields. The purifications are facile, and the reaction times are less than 5 min, which makes these fluorodecarboxylations promising for future PET-imaging applications.
