Description

Ethyl Propionate (CAS 105-37-3) is a high-purity ester compound with the molecular formula C₅H₁₀O₂. This colorless, volatile liquid exhibits a fruity, rum-like aroma, making it a valuable ingredient in flavor and fragrance formulations. Ethyl propionate is widely utilized in the food and beverage industry as a flavoring agent (FEMA No. 2456) and in the pharmaceutical sector as a solvent or intermediate. Its excellent solvency properties also lend it to applications in coatings, adhesives, and specialty chemical synthesis. Available in various grades, including FCC (Food Chemical Codex), FG (Food Grade), and analytical standards, our Ethyl Propionate meets stringent quality controls for research and industrial applications. Proper handling is required due to its flammability (UN1195).
