Pentyl formate

Pentyl formate is an organic ester compound with the molecular formula C6H12O2 and CAS number 638-49-3. It belongs to the formate ester family, formed by the condensation of formic acid and pentyl alcohol. With a molecular weight of 116.16 g/mol, this colorless liquid is classified as a flammable substance and mild irritant under GHS regulations, requiring careful handling in industrial applications.

Pentyl formate is a colorless liquid at room temperature with a characteristic fruity, banana-like odor typical of formate esters. It has limited solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound has a relatively low boiling point and high volatility, contributing to its flammable nature and classification as Flam. Liq. 3.

Pentyl formate is primarily used as a flavoring agent in the food and beverage industry due to its pleasant fruity aroma. It serves as a solvent in various industrial processes, particularly in the production of lacquers, paints, and coatings. Additionally, it finds application in the fragrance industry for perfumes and cosmetics, and as an intermediate in organic synthesis reactions.

Pentyl formate requires careful handling due to its flammable nature and irritant properties. Workers should wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and avoid ignition sources. Handle away from heat, sparks, and open flames. The compound may cause eye irritation and narcotic effects, requiring immediate attention in case of exposure.

Pentyl formate should be stored in a cool, dry, well-ventilated area away from heat sources, ignition sources, and direct sunlight. Use appropriate containers made of compatible materials and ensure proper labeling with GHS02 and GHS07 pictograms. Store separately from oxidizing agents and strong bases. Maintain storage temperature below 25°C and implement proper fire prevention measures in storage areas.

Pentyl formate exposure requires immediate first aid measures. In case of eye contact, flush immediately with plenty of water for at least 15 minutes and seek medical attention due to its Eye Irrit. 2 classification. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air immediately as it may cause narcotic effects (STOT SE 3). Remove contaminated clothing and seek medical advice if symptoms persist.

Pentyl formate disposal must comply with local and European waste regulations as a flammable and hazardous substance. It cannot be disposed of in regular waste streams or poured down drains. Contact licensed waste disposal companies for proper treatment, which may include incineration at authorized facilities. Small quantities should be collected in appropriate containers and labeled clearly for hazardous waste pickup.

Pentyl formate is classified under ADR as Class 3 (flammable liquids), Packing Group III for transportation purposes. It requires appropriate packaging, labeling, and documentation according to dangerous goods regulations. Transport vehicles must be equipped with proper safety equipment and drivers need ADR certification. Packages must display the flammable liquid hazard label and proper shipping name during transport across European roads.

Pentyl formate is regulated under European REACH and CLP regulations, requiring proper registration, classification, and labeling. It displays Warning signal word with GHS02 and GHS07 pictograms due to its flammable and irritant properties. The substance is not classified as SVHC (Substance of Very High Concern), but still requires compliance with occupational safety standards and proper risk assessment in workplace environments.
