100921-66-2 Usage
General Description
Bromo-2 butyl-3 pyridine is a chemical compound that is a derivative of pyridine, a six-membered heterocyclic ring composed of five carbon atoms and one nitrogen atom. The bromo-2 butyl-3 pyridine molecule contains a butyl group, which is a four-carbon alkyl chain, and a bromine atom attached to the second carbon of the butyl group. This chemical compound is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It can also be used as a building block in the development of other organic compounds for various industrial applications. The presence of a bromine atom in the molecule makes it reactive and useful in various chemical reactions for producing complex organic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 100921-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100921-66:
(8*1)+(7*0)+(6*0)+(5*9)+(4*2)+(3*1)+(2*6)+(1*6)=82
82 % 10 = 2
So 100921-66-2 is a valid CAS Registry Number.

ACTION DU N-BUTYLLITHIUM SUR LES BROMO-3 HALOGENO-2 PYRIDINES FLUOREE, CHLOREE ET BROMEE PRINCIPE ET ETUDE D'UNE POSSIBILITE REACTIONNELLE NOUVELLE: L'HOMOTRANSMETALLATION

Apart from the common bromine-lithium exchange reaction in brominated aromatic compounds, it is possible to obtain a lithio-derivative quite different from the one usually described in such a reaction.This new reaction, which results from a special experimental condition is called 'homotransmetalation', and it occurs when using n-buthyllithium and 3-bromo 2-halogenopyridines (1).Different behaviour is observed with the three similar compounds (1:X = F,Cl,Br).Explanations are proposed of these results.It is then possible to compare the relative stabilities of the proposed lithio-structures.It is evident that nucleophilic substitution of bromine in position 4 of the pyridine ring is easier than is usually recognised.
