Ethyl propanoate

Ethyl propanoate is an organic chemical compound with the molecular formula C5H10O2 and CAS number 105-37-3. This ester has a molecular weight of 102.13 g/mol and belongs to the class of flammable liquids (Flam. Liq. 2). It is classified as a hazardous substance requiring careful handling due to its flammable properties, indicated by the GHS02 pictogram and 'Danger' signal word.

Ethyl propanoate is a colorless liquid with a characteristic fruity, sweet odor reminiscent of rum or pineapple. It has good solubility in organic solvents like ethanol and ether but limited solubility in water. The compound has a relatively low boiling point and high volatility, contributing to its flammable nature. Its ester functional group gives it typical ester properties including moderate polarity.

Ethyl propanoate is primarily used as a flavoring agent in the food industry due to its pleasant fruity aroma. It serves as a solvent in various industrial applications including coatings, inks, and adhesives. The compound is also utilized in the fragrance industry for perfumes and cosmetics, and as an extraction solvent in analytical chemistry and pharmaceutical processes.

Ethyl propanoate must be handled with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume hoods to prevent vapor accumulation. Eliminate all ignition sources as the substance is highly flammable (Class 2). Use anti-static equipment and ensure proper grounding of containers during transfer operations to prevent static discharge.

Ethyl propanoate should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly sealed and store in original packaging or compatible containers. Maintain storage temperature below 25°C and protect from direct sunlight. Store separately from strong oxidizing agents, acids, and bases to prevent incompatible reactions.

In case of skin contact with ethyl propanoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical help if breathing difficulties occur. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Ethyl propanoate must be disposed of according to local, national, and European waste regulations as hazardous waste. Never pour down drains or release into the environment. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities may be incinerated in approved facilities with adequate emission controls. Always consult local authorities for specific disposal requirements in your region.

Ethyl propanoate is classified under ADR Class 3 (flammable liquids), Packing Group II for transport purposes. It requires appropriate hazardous goods packaging, labeling with Class 3 labels, and proper shipping documentation. Transport vehicles must comply with ADR regulations including equipment requirements and routing restrictions. Only trained personnel should handle the transportation of this flammable substance.

Ethyl propanoate is subject to European CLP Regulation for classification, labeling, and packaging as a flammable liquid. It falls under REACH regulation requirements for registration and safety data provision. The substance is not currently listed as a Substance of Very High Concern (SVHC). Specific workplace exposure limits may apply depending on national regulations in different European countries.
