Primary Uses

Ethyl Butyrate can be used as a flavoring agent (food & personal care): Key ingredient for pineapple, apple, apricot, rum, and cream flavor profiles; used in soft drinks, confectionery, baked goods, and ice cream (dosage in the mg/kg range); the essential component of "artificial pineapple flavor."
Solvent: Used in medium-to-fast-drying coatings, inks, and adhesives; offers a more pleasant odor profile than ethyl acetate.
Organic synthesis intermediate: Used in the production of butyric acid-based pharmaceuticals and pesticide side chains.
Chromatographic standard.

Safety and Physiology

Toxicity:Ethyl Butyrate is low toxicity. Oral LD₅₀ in rats ≈ 3.3 g/kg; high-concentration vapors cause dizziness and mucous membrane irritation; liquid causes moderate eye irritation; minimal percutaneous absorption.
GHS: H225 Highly flammable; H319 Causes serious eye irritation; H332 Harmful if inhaled.
Storage and Transport: UN 1180 (similar entry), Class 3, PG II; store in a cool, explosion-proof area (≤30°C); keep separate from oxidizing agents and strong bases.
