128071-77-2 Usage
General Description
4-Bromo-2-fluoropyridine-3-carboxaldehyde, also known as CAS Number 1000627-56-4, is a specialized chemical compound that belongs to the category of halopyridines. This chemical is often used in the world of scientific research, particularly in the synthesis of other complex compounds. The aromatic halogenated compound, which has a molecular formula of C6H3BrFNO, is characterized by a pyridine ring combined with bromo, fluoro, and aldehyde substituents. Pyridine compounds like this one are structurally similar to benzene and are known for their stability, versatility, and usefulness in creating other chemical entities. Its physical state is typically a clear liquid and it should be stored in a cool, dry place for optimal preservation. It can be harmful if swallowed, inhaled, or comes in contact with skin, hence, appropriate protective equipment and handling precautions should be maintained.
Check Digit Verification of cas no
The CAS Registry Mumber 128071-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,7 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128071-77:
(8*1)+(7*2)+(6*8)+(5*0)+(4*7)+(3*1)+(2*7)+(1*7)=122
122 % 10 = 2
So 128071-77-2 is a valid CAS Registry Number.

Migration du lithium en serie pyridinique: double catalyse et reformage. Acces aux derives de la bromo-2 lithio-3 pyridine et des bromo-4 halogeno-2 lithio-3 pyridines

The lithium of an organolithium-pyridinic derivative can be moved from one position to an another by an intermolecular reaction.Two new reactions are possible for pyridinic organic synthesis: the isomerisation of any lithio derivative to a more stable one, and a reaction that transforms a mixture of various bromo-lithio derivatives into a single one.The processes involved and the experimental tools used are described in terms of the 2-bromo-3-lithio- and 4-bromo-2-halogeno-3-lithiopyridines derivatives synthesis.
