Pentyl propanoate

Pentyl propanoate is an organic chemical compound with the molecular formula C8H16O2 and CAS number 624-54-4. This ester has a molecular weight of 144.21 g/mol and belongs to the class of aliphatic esters formed by the reaction between pentanol and propanoic acid. It is classified as a flammable liquid category 3 under GHS regulations, requiring careful handling due to its fire hazard properties.

Pentyl propanoate is a colorless liquid at room temperature with a characteristic fruity, apple-like odor typical of esters. It has limited solubility in water due to its organic nature but is miscible with most organic solvents including alcohols and ethers. The compound exhibits typical ester properties with moderate volatility and a relatively low flash point, contributing to its flammable liquid classification.

Pentyl propanoate is primarily used in the flavor and fragrance industry as an artificial flavoring agent, particularly for apple and fruity scents. It serves as a solvent in various industrial applications and as an intermediate in organic synthesis. The compound is also utilized in the formulation of perfumes, cosmetic products, and food additives where its pleasant fruity aroma is desired for enhancing product appeal.

Pentyl propanoate requires careful handling due to its flammable nature. Personal protective equipment should include safety goggles, chemical-resistant gloves, and adequate ventilation to prevent vapor inhalation. Keep away from heat sources, sparks, and open flames. Work in well-ventilated areas or under fume hoods to minimize exposure to vapors. Avoid skin and eye contact, and ensure proper grounding when transferring the material to prevent static discharge.

Pentyl propanoate 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 they are tightly sealed to prevent evaporation and contamination. Store separately from strong oxidizing agents and incompatible materials. Maintain storage temperature below 25°C when possible and ensure adequate fire suppression systems are available in storage areas.

In case of skin contact with pentyl propanoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist.

Pentyl propanoate must be disposed of in accordance with local and national hazardous waste regulations. Do not pour down drains or dispose of in regular waste. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities can often be recovered through distillation for reuse. Always consult local environmental authorities for specific disposal requirements and ensure proper documentation of waste disposal activities.

Pentyl propanoate is classified under ADR as Class 3 (flammable liquids), Packing Group III. It requires appropriate dangerous goods packaging, labeling with GHS02 flammable pictogram, and proper shipping documentation. Vehicles must comply with ADR regulations for Class 3 substances. Use approved containers and ensure proper segregation from incompatible materials during transport. Drivers must hold valid ADR certification for dangerous goods transportation.

Pentyl propanoate is subject to standard chemical regulations including REACH registration requirements in Europe and CLP classification as Flam. Liq. 3 with Warning signal word. It is not listed as a SVHC (Substance of Very High Concern) under REACH. Users must comply with standard chemical safety requirements, maintain safety data sheets, and follow occupational exposure guidelines. Food-grade applications may require additional food safety certifications and compliance.
