About Mesityl oxide, 98%

Mesityl oxide (CAS 141-79-7) is a carbonyl building block offered by Vaqora Chemicals (Synthesis grade) with a typical assay of 98%. Formula C6H10O, molecular weight 98.14 g/mol. Its systematic (IUPAC) name is 4-methylpent-3-en-2-one. Alternative names: 4-Methyl-3-penten-2-one and Isopropylideneacetone.

The material typically appears as a colorless to light yellow liquid. Solubility: soluble (water). Store in a cool, well-ventilated place, away from sources of ignition, with the container tightly sealed. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span organic synthesis, condensation and reductive amination, API intermediates and solvent and extraction work. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Mesityl oxide in 500 mL and 180 kg packs with a batch-specific COA, and ship to customers worldwide.
