Ethyl Acetate

Product Overview

Ethyl Acetate (C₄H₈O₂) is a colorless, volatile ester known for its characteristic sweet, fruity odor and excellent solvency properties. Manufactured to Reagent Grade specifications, this product ensures high purity with minimal impurities, making it suitable for critical industrial and analytical applications.

With a boiling point of 77.1°C, Ethyl Acetate evaporates rapidly, promoting fast curing in coatings and efficient solvent turnover in laboratory workflows. It is miscible with common organic solvents like ethanol, ether, and chloroform, while maintaining low water solubility. This profile makes it the preferred solvent for resins, adhesives, lacquers, and liquid-liquid extractions.

For quality control and chromatography, its low acidity (≤0.0003 meq/g) and stable refractive index provide consistent baselines and reproducibility. Stored properly, it offers a shelf life of up to 24 months, supporting reliable inventory management for manufacturing and research facilities.

Safety Precautions

Ethyl Acetate is highly flammable. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep containers tightly closed when not in use. Use only with adequate ventilation or inside a fume hood. Standard Personal Protective Equipment (PPE), including chemical-resistant gloves and splash goggles, is required during handling.

Emergency Response: In case of eye or skin contact, flush immediately with water. If inhaled, move to fresh air. Refer to the Safety Data Sheet (SDS) for detailed safety, handling, and emergency procedures.
