Application

Neopentyl alcohol serves as a key building block in the synthesis of neopentyl esters, which are used as plasticizers and lubricant additives due to their thermal stability. It is employed in pharmaceutical intermediates where its hindered structure prevents unwanted side reactions. The compound also finds use in polymer chemistry as a chain terminator or modifier for polyesters and alkyd resins.
