Amyl formate

About Amyl formate

Amyl formate is an ether building block in Synthesis grade carrying the CAS registry number 638-49-3 at a purity of ≥95%. With the molecular formula C6H12O2, it has a molar mass of 116.16 g/mol. Systematically, it is named pentyl formate. Common synonyms include Formic acid amyl ester and Formic acid, pentyl ester.

The material typically appears as a colourless to very faint yellow liquid. Reported physical data include a boiling point of 132 °C and a density of 0.884 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.

It is commonly used for paints, coatings and inks and solvent and extraction work. Buyers come mainly from pharmaceutical manufacturing, academic and industrial research and paints and coatings.

We offer Amyl formate in 500 g, 5 x 1 kg and 25 kg packs with a batch-specific COA, and ship to customers worldwide.
