1,2-dimethyl propyl 2-butenoate

1,2-dimethyl propyl 2-butenoate is a chemical ester compound also known synonymously as but-2-enoic acid 1,2-dimethylpropyl ester and 1,2-dimethylpropyl crotonate. This ester is characterized by a clear appearance and exhibits a distinctive fruity and winey aroma with woody and green undertones. It is part of a broader class of volatile esters known for their varied odor profiles. The compound's molecular structure confers limited solubility in water, while it is soluble in alcohol solvents, a property relevant in its handling and use. While it can be sourced or synthesized through typical esterification reactions between the corresponding alcohol and but-2-enoic acid, it is primarily referenced for informational purposes and is not commonly employed commercially in fragrance or flavor applications. Additional details and chemical identifiers can be accessed via PubChem for structural and physicochemical data.

This compound occurs primarily as a synthetic ester without documented natural biological sources. Its main application is informational, as it is not utilized for fragrance or flavor purposes. The compound's odor characteristics might be relevant to researchers studying ester odor profiles or synthetic fragrance chemistry; however, it lacks authorized use in commercial formulations. Regulatory frameworks such as REACH (EU) include registration requirements for such chemicals, even when actual use in consumer products is absent. Its profile as a fruity and winey smelling ester suggests potential for research into analogous compounds with sensory applications, but no formal commercial or industrial uses have been established to date.

1,2-dimethyl propyl 2-butenoate exhibits distinct solubility behavior, being soluble in alcohol solvents yet insoluble in water. This solubility profile influences its handling properties and potential formulation compatibility, particularly in alcoholic or organic media. The compound's molecular structure, featuring a crotonate ester moiety, contributes to its volatility and aromatic properties. It possesses a fruity, winey odor with woody and green nuances that arise due to its specific ester functionality and carbon skeleton substitution. These properties affect its behavior in vapor phase and solution and define its sensory character despite its limited use. No significant safety hazards are classified under standard occupational guidelines, and toxicological data remain incomplete or undetermined.
