3-Amino-phenylacetylene

Product Overview

3-Amino-phenylacetylene, also known as 3-ethynylaniline or m-aminophenylacetylene, is an aromatic organic compound containing both an amino group and a terminal alkyne group. The combination of these two functional groups makes it a useful building block in organic synthesis, pharmaceutical intermediate research, and specialty chemical development.

Its molecular structure provides two different reactive sites for chemical modification. The amino group can participate in various reactions involving nitrogen-containing compounds, while the terminal alkyne group offers opportunities for carbon-carbon bond formation and further molecular functionalization. This dual functionality makes 3-Amino-phenylacetylene valuable for preparing more complex aromatic structures.

Chemical Identification and Specifications

Molecular Structure and Chemical Characteristics

The molecular structure of 3-Amino-phenylacetylene consists of a benzene ring substituted with an amino group and an ethynyl group at the meta positions. This arrangement allows the molecule to participate in different chemical transformations through its two functional groups.

The amino group provides a reactive nitrogen-containing site that can be involved in selected condensation, coupling, and derivatization reactions. Meanwhile, the terminal alkyne group can participate in catalytic coupling and cycloaddition reactions. Researchers can use these complementary functionalities to introduce additional structural complexity into aromatic molecules.

Because both groups are present in the same molecule, reaction selectivity and compatibility should be considered when designing synthetic routes. Appropriate catalysts, reagents, and reaction conditions are important for controlling transformations and obtaining the desired products.
