2(3H)-Furanone, 5-heptyldihydro-, commonly known as Gamma-Undecalactone or Aldehyde C-14, is a prominent lactone widely recognized for its intense, sweet, and fruity aroma. This colorless to pale yellow liquid is characterized by a distinctive scent profile that closely mimics the fragrance of ripe peaches and apricots. Chemically, it is a cyclic ester that exhibits excellent stability across a range of pH levels, making it a versatile component in various chemical formulations.
In industrial and research contexts, this compound is valued for its high tenacity and low odor threshold. It is typically handled as a stable organic liquid, requiring storage in tightly sealed containers away from direct light and heat to prevent degradation. Its unique olfactory properties and chemical robustness ensure its continued importance as a benchmark ingredient in the development of sophisticated aromatic and flavor profiles.
