2-(2-bromo-2-phenyl-vinyl)-pyridine is an organic compound characterized by a pyridine ring, which is a six-membered aromatic ring containing two nitrogen atoms. In this specific compound, the pyridine ring is substituted at the 2-position with a 2-bromo-2-phenyl-vinyl group. The 2-bromo-2-phenyl-vinyl moiety consists of a vinyl group (a carbon-carbon double bond), a bromine atom, and a phenyl ring (a benzene ring). This chemical structure endows the compound with unique electronic and steric properties, making it a potentially useful building block in the synthesis of more complex molecules, such as pharmaceuticals and materials with specific optical or electronic properties. The presence of the bromine atom also suggests that 2-(2-bromo-2-phenyl-vinyl)-pyridine could be involved in reactions where halogen atoms are exchanged or used as a leaving group in substitution reactions.
The CAS Registry Mumber 5222-92-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,2 and 2 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5222-92: (6*5)+(5*2)+(4*2)+(3*2)+(2*9)+(1*2)=74 74 % 10 = 4 So 5222-92-4 is a valid CAS Registry Number.
