CAS 766-96-1: 1-bromo-4-ethynylbenzene

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).

4-Bromophenylacetylene, is used as the starting material for second-order nonlinear optical materials, heterocyclotriynes, and unsymmetrical 1,4-diarylbutadiynes.
