Description

2-Butyne-1,4-diol is used as a precursor to prepare 1,4-butanediol, 2-butene-1,4-diol and mucochloric acid. It is also used in textile additives, corrosion inhibitors, plasticizers, synthetic resins and polyurethanes. It is an important raw material of vitamin B6. Further, it is used for brightening, preserving and inhibiting nickel plating. In addition, it is used in biological studies for nematocidal activity.

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.
