1-ethyl propyl 2-butenoate

1-ethyl propyl 2-butenoate is an ester derived from but-2-enoic acid featuring a 1-ethylpropyl group. It appears as a chemical substance characterized by a distinct fatty and oily odor profile with fishy and chemical nuances at standard concentrations. Known also under synonyms like 1-ethylpropyl crotonate and but-2-enoic acid 1-ethylpropyl ester, it is structurally identified in the PubChem database. Sourced typically via chemical synthesis, it is not naturally abundant. Due to its particular sensory properties and technical profile, it serves primarily scientific interest rather than commercial application in consumer products.

1-ethyl propyl 2-butenoate does not naturally occur in biological systems but is a synthetic ester used for informational purposes in chemical databases and research. Its application is limited as it is not employed in fragrance or flavor industries under current standards. The compound's usage adheres to safety guidelines outlined under REACH (EU) regulations, emphasizing absence of classification for use in consumer products and restricting its employment exclusively to informational or experimental contexts.

This ester dissolves readily in alcohol but does not dissolve in water, indicative of its hydrophobic and lipophilic character influencing formulation potential. Its fatty and oily odor properties suggest volatility at ambient temperature, contributing to its sensory impact. The chemical structure lends to moderate stability without noted hazardous classifications, making it suitable only for controlled scientific applications rather than commercial product development.
