4-Hydroxyoctanoic acid lactone, also recognized by the common name gamma-octalactone, is a cyclic ester belonging to the lactone family. Identified by CAS 104-50-7, this compound is characterized by its distinctively sweet, creamy, and coconut-like aroma profile, often accompanied by subtle fruity undertones reminiscent of apricot or peach. Physically, it presents as a colorless to pale yellow liquid that is stable under standard storage conditions but should be handled with general industrial safety precautions, including adequate ventilation and protective equipment.
In the chemical and manufacturing sectors, this material is valued for its high olfactory potency and its ability to blend seamlessly with other aromatic compounds. Its chemical structure allows for versatility in various organic syntheses, serving as a building block for more complex molecules. Due to its robust organoleptic properties, it remains a staple ingredient for formulators seeking to impart rich, lactonic notes to a wide range of consumer and industrial products.
