Dichloro-fluoro-acetic acid tert-butyl ester, also known as 2,2-dichloro-1,1,1-trifluoroethyl tert-butyl ether or DBF-TBE, is a synthetic chemical compound with the molecular formula C5H7Cl2F3O2. It is a colorless liquid with a density of 1.34 g/cm3 and a boiling point of 120-121°C. dichloro-fluoro-acetic acid tert-butyl ester is primarily used as a herbicide, specifically as a selective post-emergence herbicide for controlling broadleaf and grassy weeds in various crops, including corn, soybeans, and cereals. It works by inhibiting the enzyme enolpyruvylshikimate-3-phosphate synthase (EPSPS) in plants, which is essential for the synthesis of the amino acids phenylalanine, tyrosine, and tryptophan. This inhibition disrupts the plant's growth and ultimately leads to its death. Due to its effectiveness and low mammalian toxicity, DBF-TBE has become an important tool in modern agriculture for managing weed populations and ensuring crop productivity.

686-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 686-97-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.Calculate Digit Verification of CAS Registry Number 686-97:
(5*6)+(4*8)+(3*6)+(2*9)+(1*7)=105
105 % 10 = 5
So 686-97-5 is a valid CAS Registry Number.
