Although the simple distillation is possible, these aliphatic α-formyl esters are relatively unstable and have to be stored in a refrigerator (ca. - 10 °C) to avoid decomposition. Within ca. 1 week, they should be transformed to the corresponding stable enol tosylates. Aromatic α-formyl esters are stable enough for refrigerator storage for some weeks. These α-formyl esters will be useful for the active methylene precursor.
