General Description
1,2-Dibromo-3-chloro-benzene is a chemical compound with the molecular formula C6H3Br2Cl. It is a halogenated benzene derivative, containing two bromine atoms and one chlorine atom attached to the benzene ring. 1,2-DIBROMO-3-CHLORO-BENZENE is mainly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It is also used as a starting material for the production of other chemicals, including dyes, polymers, and fragrances. 1,2-Dibromo-3-chloro-benzene is a colorless to pale yellow liquid with a strong odor, and it is considered to be harmful if swallowed, inhaled, or exposed to the skin or eyes. It is important to handle and use this chemical with proper safety precautions and protective equipment to prevent any potential health hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 104514-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,1 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104514-49:
(8*1)+(7*0)+(6*4)+(5*5)+(4*1)+(3*4)+(2*4)+(1*9)=90
90 % 10 = 0
So 104514-49-0 is a valid CAS Registry Number.

Efficient and complementary methods offering access to synthetically valuable 1,2-dibromobenzenes

1,2-Dibromobenzenes are highly valuable precursors for various organic transformations, in particular, reactions based on the intermediate formation of benzynes. This report describes short sequences for the synthesis of various derivatives based on regioselective bromination, ortho-metalation, and halogen/metal permutations. 1,2-Dibromo-3-iodobenzene (2f), 1,2-dibromo-4- iodobenzene (4c), and 2,3-dibromo-1,4-diiodobenzene (5e) act as intermediates in these syntheses. Bromo-iodoarenes have been synthesized by short and regioselective bromination or iodination sequences that combine ortho-metalation, halo-desilylation, diazotation, or bromination reactions of anilines. These polyhalo derivatives were then used as key intermediates to access a wide range of functionalized 1,2-dibromobenzenes by chemoselective organometallic reactions. Copyright
