5-Hydroxyoctanoic acid lactone Usage And Synthesis
DescriptionMay be synthesized from 5-hydroxyoctanoic acid by reduction with NaBH4 in water; by microbiological reduction of the corresponding keto acid; from 5-hydroxyoctanoic methyl amide by alkaline saponification, using Ba(OH)2.
Chemical PropertiesΔ-Octalactone has a sweet, fatty, coconut, tropical, dairy odor.
OccurrenceReported found as a volatile flavor component in coconut oil, butterfat, milk fat, the essence of the Blenheim variety of apricot, and pineapple, yellow passion fruit, cranberry, currant buds, papaya, peach, raspberry, strawberry, bilberry, plum, tomato, many cheeses, chicken fat, cooked beef, pork and mutton, rum, sherry, white wine, tea, coconut products, passion fruit, mango, prickly pear, loquat, mountain papaya, nectarine, cape gooseberry and rooibus tea (Aspalathus linearis).
Usesdelta-Octanolactone is a important organic intermediate. It can be used in agrochemical, pharmaceutical and dyestuff field.
PreparationFrom 5-hydroxyoctanoic acid by reduction with NaBH4 in water; by microbiological reduction of the corresponding keto acid; from 5-hydroxyoctanoic methyl amide by alkaline saponification, using Ba(OH)2.
DefinitionChEBI: Delta-octanolide is a delta-lactone.
