Propyl formate

Propyl formate is an organic chemical compound with the molecular formula C4H8O2 and CAS number 110-74-7. This ester has a molecular weight of 88.11 g/mol and belongs to the formate family of compounds. It is classified as a flammable liquid with specific hazard properties including eye irritation and specific target organ toxicity. The substance requires careful handling due to its flammable nature and potential health effects upon exposure.

Propyl formate is a colorless liquid with a characteristic fruity, pleasant ester odor reminiscent of plums or apples. It has a relatively low boiling point and is moderately soluble in water while being miscible with most organic solvents. The compound exhibits typical ester properties and has a density lower than water. Its volatility and flammable characteristics make it important to consider ventilation and ignition sources during handling.

Propyl formate is primarily used as a solvent in various industrial applications including coatings, inks, and adhesive formulations. It serves as a flavoring agent in the food industry due to its pleasant fruity aroma and is utilized in perfumery and cosmetic applications. The compound is also employed as an intermediate in organic synthesis and as a solvent for cellulose-based materials and resins in manufacturing processes.

Propyl formate requires appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume extraction systems due to vapor hazards. Eliminate ignition sources as the substance is highly flammable. Avoid breathing vapors and ensure emergency eyewash stations and safety showers are accessible in work areas.

Propyl formate must be stored in tightly sealed containers in cool, dry, well-ventilated areas away from heat sources, sparks, and open flames. Storage areas should be equipped with appropriate fire suppression systems and maintained below recommended temperature limits. Keep containers away from incompatible materials such as strong oxidizers and acids. Ensure proper grounding and bonding procedures when transferring the material to prevent static electricity buildup.

Propyl formate exposure requires immediate action depending on the contact route. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention due to its eye irritant properties. If skin contact occurs, wash thoroughly with soap and water. In case of inhalation, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention while providing safety data sheet information to medical personnel.

Propyl formate disposal must comply with local, national, and international waste regulations as it is classified as hazardous waste. The substance should never be poured down drains or released into the environment. Disposal should be arranged through licensed hazardous waste contractors who can ensure proper treatment, incineration, or recycling. Empty containers may retain hazardous residues and require proper cleaning or disposal through appropriate waste management channels.

Propyl formate is classified under ADR as Class 3 (flammable liquids), Packing Group II, indicating moderate danger level for transportation. Packages must comply with UN specifications and bear appropriate hazard labels including flammable liquid markings. Transport vehicles require proper ventilation, fire extinguishing equipment, and trained drivers with ADR certification. Shipping documentation must include proper shipping names, hazard classifications, and emergency response information.

Propyl formate is regulated under European REACH and CLP regulations requiring registration and proper classification and labeling. The substance is not currently listed as a Substance of Very High Concern (SVHC). Suppliers must provide safety data sheets and ensure proper hazard communication through GHS pictograms GHS02 and GHS07 with the signal word 'Danger'. Users must comply with occupational exposure limits and workplace safety requirements in their respective jurisdictions.
