General description

Pentyl acetate is a straight chain ester. It is an odorant and its odor threshold has been evaluated by sensory panel methods. High pressure phase behavior of type I has been reported for its binary mixtures with CO2. Solubility of these solvent mixtures was observed to increase with the rise in temperature at constant pressure.

Application

Pentyl acetate may be used as odorant to compose the library of odorants to evaluate the responses of olfactory sensory neurons (OSNs) to various odorants (having different structures and odors).
Banana essence. Used as test odorant in studies of olfactory function and in studies of the psychosocial effects of odor.
