3-methylbutyl formate

3-methylbutyl formate is an organic chemical compound with the molecular formula C6H12O2 and CAS number 110-45-2. It belongs to the ester family, formed by the combination of formic acid and 3-methylbutanol (isoamyl alcohol). With a molecular weight of 116.16 g/mol, this compound is classified as a flammable liquid that poses eye irritation and specific target organ toxicity risks. It requires careful handling due to its hazardous properties indicated by GHS02 and GHS07 pictograms.

3-methylbutyl formate is a colorless to pale yellow liquid at room temperature with a characteristic fruity, banana-like odor typical of formate esters. It has low solubility in water but is miscible with most organic solvents including alcohols and ethers. The compound has a relatively low boiling point and high volatility, contributing to its flammable nature. Its density is lower than water, and it exhibits typical ester chemical reactivity including hydrolysis under acidic or basic conditions.

3-methylbutyl formate is primarily used as a flavoring agent in the food industry due to its pleasant fruity aroma reminiscent of bananas and apples. It serves as a solvent in various industrial applications, particularly in coatings, paints, and adhesives formulations. The compound is also utilized in the fragrance industry for perfumes and cosmetic products. Additionally, it finds application as an intermediate in organic synthesis and as a component in specialty chemical formulations requiring its specific solvent properties.

3-methylbutyl formate requires careful handling due to its flammable and irritating properties. Always wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Keep away from ignition sources, heat, and sparks. Use explosion-proof electrical equipment when handling larger quantities. Ensure proper grounding and bonding during transfer operations to prevent static electricity buildup.

3-methylbutyl formate must be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and ignition sources. Use tightly sealed containers made of compatible materials to prevent vapor escape and contamination. Store separately from strong oxidizing agents, acids, and bases to avoid incompatible reactions. Maintain storage temperatures below 25°C when possible and ensure adequate fire suppression systems are available. Regular inspection of containers for leaks or damage is essential for safe storage management.

In case of eye contact with 3-methylbutyl formate, immediately flush with plenty of clean water for at least 15 minutes and seek medical attention. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water. If inhaled, move the person to fresh air immediately and seek medical help if breathing difficulties occur. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult the safety data sheet for specific emergency procedures.

3-methylbutyl formate waste must be disposed of in accordance with local, national, and EU waste regulations. The substance should be collected in appropriate containers and handed over to authorized waste disposal companies specializing in hazardous chemical waste. Do not discharge into drains, soil, or water bodies. Incineration at licensed facilities with appropriate emission controls is typically the preferred disposal method. Empty containers should be properly cleaned and disposed of according to local regulations for hazardous waste packaging materials.

3-methylbutyl formate is classified as ADR Class 3 (flammable liquids), Packing Group III for transportation purposes. It must be transported in approved packaging that meets UN specification requirements and properly labeled with appropriate hazard labels. Transport vehicles must comply with ADR regulations including proper ventilation, fire extinguishing equipment, and emergency response information. Only trained and certified drivers should transport this material, and all transport documentation must accurately reflect the hazardous nature of the cargo.

3-methylbutyl formate is subject to various European regulations including REACH registration requirements and CLP classification and labeling obligations. It is not identified as a Substance of Very High Concern (SVHC) under REACH. The compound must be classified and labeled according to CLP regulation with appropriate hazard statements and precautionary measures. Food-grade applications are subject to additional food safety regulations. Industrial users must comply with occupational health and safety requirements and maintain proper risk assessments for workplace exposure.
