About Dibutyl phosphate, ≥97%

Dibutyl phosphate (CAS 107-66-4) is an organic building block offered by Vaqora Chemicals, specified at 97% purity. The compound has the formula C8H19O4P, corresponding to a molecular weight of 210.21 g/mol. The IUPAC name is dibutyl hydrogen phosphate. Alternative names: Di-n-butyl phosphate and Phosphoric acid, dibutyl ester.

It is supplied as a colourless to light yellow to light orange liquid. Reported physical data include a melting point of -13 °C and a density of 1.06 g/mL at 20 °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.

Key uses span catalysis and polymer and resin production. Typical end-use sectors are pharmaceutical manufacturing, academic and industrial research and polymers and plastics.

Standard pack sizes are 100 mL, 250 mL, 500 mL and 1 L, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
