About Tiglic acid, 98%

Tiglic acid (CAS 80-59-1) is a carboxylic acid offered by Vaqora Chemicals, specified at 98% purity. Its molecular formula is C5H8O2 and its molecular weight is 100.12 g/mol. The IUPAC name is (E)-2-methylbut-2-enoic acid. Alternative names: trans-2,3-Dimethylacrylic acid and Tiglinic acid.

It is supplied as white to almost white powder or crystals. Literature values give a melting point of 64 °C and a boiling point of 82 °C/8 mmHg. Store it at 0–10 °C, in a tightly closed container. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for organic synthesis and API synthesis. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

We offer Tiglic acid in 5 g and 25 g packs with a batch-specific COA, and ship to customers worldwide.
