About Butyric anhydride, 99%

Listed under CAS 106-31-0, Butyric anhydride is an acylating agent available from Vaqora Chemicals (Synthesis grade) at a purity of 99%. Its molecular formula is C8H14O3 and its molecular weight is 158.19 g/mol. Its systematic (IUPAC) name is butanoyl butanoate. Alternative names: Butanoic anhydride and n-Butyric anhydride.

It is supplied as a clear colourless liquid. Literature values give a melting point of -75 -66 °C and a density of 0.967 g/mL at 25 °C. Store in a cool, well-ventilated place, away from sources of ignition, with the container tightly sealed. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include dyes and pigments manufacture and solar and photovoltaic research. Buyers come mainly from pharmaceutical manufacturing, academic and industrial research and textiles and dyeing.

Standard pack sizes are 500 mL, 5 L and 200 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
