Chemical Properties

3-Heptanol has a powerful, herbaceous odor and a pungent, slightly bitter taste.

Occurrence

Reported found in banana, papaya, French fried potato, peppermint oil, butter, fried or grilled beef, cognac, coffee, peated malt and rooibus tea (Aspalathius linearis)

Uses

Flotation frother, solvent and diluent in organic coatings, intermediates.

Uses

3-Heptanol can be used:

3-Heptanol is the main biotransformation product of n-heptane.

Hazard

Toxic by ingestion. Moderate fire risk.

Biochem/physiol Actions

Odor at 1.0%

Metabolism

In the rabbit, heptan-l-ol is metabolized partly by direct conjugation with glucuronic acid to form an ether glucuronide and mainly by oxidation to the carboxylic acid, which either undergoes further oxidation to CO₂ or forms an ester glucuronide
