Butyl (2S)-2-hydroxybutanoate

The presence of a defined (2S) stereochemistry makes it valuable where enantioselective purity is critical.This compound functions as a building block, not a finished drug. Anyone treating it as an API is misunderstanding its role in the value chain. Butyl (2S)-2-hydroxybutanoate is a chiral hydroxy ester used as a specialty chemical intermediate in pharmaceutical and fine-chemical synthesis.
