About Meldrum's acid, ≥98%

Meldrum's acid is an ester carrying the CAS registry number 2033-24-1 with a typical assay of ≥98%. Its molecular formula is C6H8O4 and its molecular weight is 144.12 g/mol. Its systematic (IUPAC) name is 2,2-dimethyl-1,3-dioxane-4,6-dione. It is also known as 1,3-Dioxane-4,6-dione, 2,2-dimethyl- or Isopropylidene malonate.

In its supplied form it is white to beige powder or crystal or chunks. Literature values give a melting point of 92-96 °C. Store it at 2–8 °C, in a tightly closed container. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span organic synthesis and API synthesis. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 25 g, 100 g, 500 g and 5 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
