Abstract
In the method of the invention, hydroxypivalaldehyde (3-hydroxy-2,2-dimethylpropanal) and/or its dimer is stored under solid conditions containing an amount of water. By storing such solid conditions, hydroxypivalaldehyde and/or its dimer is stored for a long period of time without reducing its purity.
