Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its structure allows for functionalization in multi-step reactions, making it valuable in creating active pharmaceutical ingredients (APIs). Commonly employed in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules due to its carboxylic acid groups and chiral potential. Also utilized in the development of specialty polymers and as a building block in medicinal chemistry research.
