General Description
Pale yellow or colorless liquid.
Reactivity Profile
D-CARVONE(2244-16-8) may be sensitive to prolonged exposure to light and air. Incompatible with strong oxidizing agents and strong reducing agents
Air & Water Reactions
May be sensitive to prolonged exposure to light and air. Insoluble in water.
Potential Exposure
Carvone is found in various natural
oils, including caraway and dillseed; mandarin peel and
spearmint oils. A food additive, it is used in flavoring
liqueurs; in perfumes and soaps.
Fire Hazard
This chemical is combustible.
First aid
Skin Contact: Flood all areas of body that have
contacted the substance with water. Don’t wait to remove
contaminated clothing; do it under the water stream. Use
soap to help assure removal. Isolate contaminated clothing
when removed to prevent contact by others. Eye contact:
Remove any contact lenses at once. Flush eyes well with
copious quantities of water or normal saline for at least
2030 minutes. Seek medical attention. Inhalation: Leave
contaminated area immediately; breathe fresh air. Proper
respiratory protection must be supplied to nay rescuers. If
coughing, difficult breathing, or any other symptoms
develop, seek medical attention at once, even if symptoms
develop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk
to dilute the substance. Assure that the person’s airway is
unobstructed and contact a hospital or poison center immediately for advice on whether or not to induce vomiting.
Storage: (1) Color code—Blue: Health Hazard/Toxics/
Poisons: Store in a secure poison location. (2) Color
code—Red: Flammability Hazard: Store in a flammable
liquid storage area or approved cabinet away from ignition
sources and corrosive and reactive materials. Store in a
cool, dry place, or in a refrigerator.

Description
Carvone is a pale yellow to white clear liquid.Molecular weight=150.22; Boiling point=230℃; Flashpoint=93℃. Hazard Identification (based on NFPA 704 MRating System): Health 2, Flammability 2, Reactivity 0.
Chemical Properties
Caravone occurs in different forms. l-Carvone exhibits odor of spearmint, while d-carvone exhibits odor reminiscent
of caraway.
Chemical Properties
Carvone is a pale yellow to white clear liquid.
Chemical Properties
colourless or pale yellow liquid
Occurrence
The optically active and inactive forms have been reported among the constituents of about 70 essential oils.
The dextro form is present in carvi, Antheum graveolens, Antheum sowa, Lippia carviodora, Mentha arvensis, etc. The levo form is
present in Metha vifidis var. crispa, Mentha longifolia from South Africa, Eucalyptus globules and several mint species. The racemic
form is present in ginger grass, Litsea gutalemaleusis, lavender and Artemisia ferganensis. Reported found in citrus oil and juice
(lemon, lime, orange), celery seed, anise, clove, coriander seed, calamus, caraway herb and dill seed.
Uses
(S)-(+)-Carvone can be used as a starting material to synthesize:
- (-)-Samaderine Y, a pentacyclic quassinoid.
- (-)-Ambrox, a terpenoid responsible for the odor of ambergris.
- 3β-Acetoxydrimenin (a sesquiterpene) via conjugated addition of potassium cyanide followed by base catalyzed Robinson annulation reaction.
- Thapsigargin family members such as trilobolide, nortrilobolide, and thapsivillosin F.
Definition
ChEBI: A carvone having (S) configuration.

Detection: d-Carvone: 6.7 to 820 ppb; l-carvone: 2.7 to 600 ppb
Flammability and Explosibility
Notclassified
Synthesis
Carvone occurs in the dextro, levo and racemic form; l-carvone can be isolated from the essential oil of spearmint or
is commercially synthesized from d-limonene; d-carvone is usually prepared by fractional distillation of oil of caraway, also from
dillseed and dillweed oils, but this type differs in odor and flavors.
