CAS 766-96-1

1-bromo-4-ethynylbenzene

Description:

1-Bromo-4-ethynylbenzene, with the CAS number 766-96-1, is an organic compound characterized by the presence of a bromine atom and an ethynyl group attached to a benzene ring. This compound features a linear alkyne functional group (ethynyl) at the para position relative to the bromine substituent on the aromatic ring. It is typically a colorless to pale yellow liquid or solid, depending on its purity and temperature. The presence of the bromine atom enhances its reactivity, making it useful in various chemical reactions, including nucleophilic substitutions and coupling reactions. 1-Bromo-4-ethynylbenzene is also notable for its applications in organic synthesis, particularly in the preparation of more complex aromatic compounds and materials. Its physical properties include moderate solubility in organic solvents, and it may exhibit moderate volatility. As with many brominated compounds, it is important to handle it with care due to potential health and environmental hazards.

4-Bromophenylacetylene

CAS: 766-96-1

4-Bromophenylacetylene is a molecule that can be activated by nucleophilic attack, which is the process of reacting with a nucleophile. It is used in clinical studies to determine the activity of pancreatic lipase in humans and animals. 4-Bromophenylacetylene has been shown to have a high degree of regiospecificity, meaning that it only reacts with certain carbon atoms on the molecule, and not all of them. This allows for selective reactions to take place. 4-Bromophenylacetylene also reacts with amines, which are organic molecules containing nitrogen and hydrogen, through an X-ray absorption process. X-ray absorption is defined as an x-ray photon being absorbed by an electron in a molecule, causing the electron to change its energy level and state. The energy level and state changes are characterized by x-ray emission spectroscopy (XES).
