29604-75-9 Usage
General Description
1-Chloro-2,4-dibromobenzene is a chemical compound with the molecular formula C6H3Br2Cl. It is a colorless to pale yellow liquid with a strong, sweet odor. It is mainly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. Its chemical structure is composed of a benzene ring with a chlorine atom and two bromine atoms attached at the 1 and 4 positions, respectively. It is a highly reactive compound and should be handled with care due to its potential health and environmental hazards. Additionally, it is important to follow proper safety protocols and regulations when working with 1-Chloro-2,4-dibromobenzene to prevent any potential harm or risks associated with its use.
Check Digit Verification of cas no
The CAS Registry Mumber 29604-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,0 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 29604-75:
(7*2)+(6*9)+(5*6)+(4*0)+(3*4)+(2*7)+(1*5)=129
129 % 10 = 9
So 29604-75-9 is a valid CAS Registry Number.

N-halosuccinimide/BF3-H2O, efficient electrophilic halogenating systems for aromatics

N-Halosuccinimides (NXS, 1) are efficiently activated in trifluoromethanesulfonic acid and BF3-H2O, allowing the halogenations of deactivated aromatics. Because BF3-H2O is more economic, easy to prepare, nonoxidizing, and offers sufficiently high acidity (-H0 ≈ 12, only slightly lower than that of trifluoromethanesulfonic acid), an efficient new electrophilic reagent combination of NXS/BF3-H2O has been developed. DFT calculations at the B3LYP/6-311++G**//B3LYP/6-31G* level suggest that protonated N-halosuccinimides undergo further protosolvation at higher acidities to reactive superelectrophilic species capable either in the transfer of X+ from the protonated forms of NXS to the aromatic substrate or in forming a highly reactive and solvated X+ which would readily react with the aromatic substrates. Structural aspects of the BF 3-H2O complex have also been investigated.
