High-purity 1-butyne (C₄H₆) gas supplied from China for chemical synthesis, organic reactions, and specialty applications.
High-purity 1-butyne (C₄H₆ / ethyl acetylene) for organic synthesis, chemical intermediate production, and specialty gas applications.
1-Butyne, also known as ethyl acetylene, is a colorless gas with a characteristic odor at room temperature. As a terminal alkyne, it is insoluble in water but soluble in ethanol, ether, and most organic solvents. Its chemical structure features a reactive carbon-carbon triple bond, making it a valuable building block for various organic synthesis reactions. 1-Butyne is used as an intermediate in the production of fine chemicals, pharmaceuticals, agrochemicals, and specialty materials. It also serves as a precursor for synthesizing more complex organic compounds, typically transported as a liquefied compressed gas.
