Application:	2,2-Dimethyl-1,3-dioxane-4,6-dione was used in the synthesis of: • macrocyclic β-keto lactone • 4-pyridyl-substituted heterocycles • 2-substituted indoles • isofraxidin.
General description:	2,2-Dimethyl-1,3-dioxane-4,6-dione (Meldrum′s acid) is widely used in organic synthesis, especially for multiple C-C bond formations due to its adequate acidity (pK_a 4.83) and steric rigidity. Knoevenagel condensation reaction between aldehydes and Meldrum′s acid are accelerated in ionic liquids. Meldrum′s acid is used as a valuable starting material to synthesize heterocycles and as intermediates in organic synthesis reactions.
Packaging:	10, 25, 100 g in glass bottle
