2-Butyne is used to synthesize alkylated hydroquinones in the total synthesis of Vitamin E. It is also used as pharmaceutical intermediates.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
2-Butyne is used to synthesize alkylated hydroquinones in the total synthesis of Vitamin E. It is also used as pharmaceutical intermediates.
Solubility
Not miscible in water.
Notes
Avoid extremes of temperature and direct sunlight. Heat-sensitive. Avoid contact with oxidizing materials. Incompatible with Halogens. Chlorinated solvents.
