3-methylpentanoic acid

3-methylpentanoic acid is a branched-chain carboxylic acid with the molecular formula C6H12O2 and CAS number 105-43-1. This organic compound has a molecular weight of 116.16 g/mol and features a pentanoic acid backbone with a methyl substitution at the third carbon position. It belongs to the family of aliphatic carboxylic acids and exhibits typical acid properties including the ability to form salts and esters.

3-methylpentanoic acid is typically a colorless to pale yellow liquid at room temperature with a characteristic pungent, rancid odor typical of carboxylic acids. The compound has moderate water solubility due to its carboxylic acid group, while being more soluble in organic solvents like ethanol and ether. Its branched structure affects its boiling point and viscosity compared to straight-chain pentanoic acid derivatives.

3-methylpentanoic acid is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a building block for the production of esters, amides, and other derivatives used in flavor and fragrance industries. The compound is also utilized in research applications and as a precursor for specialty chemicals, particularly in the development of bioactive compounds and pharmaceutical intermediates.

3-methylpentanoic acid should be handled with standard laboratory safety practices including wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and lab coats. Work in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Avoid direct skin and eye contact, and ensure proper training on handling procedures. Keep containers tightly closed when not in use and away from incompatible materials.

3-methylpentanoic acid should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent contamination and vapor release. Store away from strong bases, oxidizing agents, and reactive metals that could react with the carboxylic acid. Use appropriate secondary containment and ensure storage areas comply with local chemical storage regulations and fire safety requirements.

In case of skin contact with 3-methylpentanoic acid, immediately remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. For eye contact, rinse immediately with water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. If swallowed, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for complete first aid procedures.

3-methylpentanoic acid waste must be disposed of according to local, national, and international waste regulations. The compound should be collected in appropriate waste containers and handed over to licensed waste disposal companies. Do not discharge into drains, water bodies, or soil. Neutralization may be possible under controlled conditions by qualified personnel, but professional waste management services are recommended to ensure regulatory compliance and environmental protection.

3-methylpentanoic acid is classified as ADR Class 8 (corrosive substances), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with appropriate labeling and documentation. Transport vehicles must comply with ADR regulations for corrosive materials, including proper placarding and driver certification. Ensure proper segregation from incompatible materials during transport and follow all applicable shipping regulations for hazardous materials.

3-methylpentanoic acid is subject to standard chemical regulations including REACH registration requirements in Europe for quantities above specified thresholds. It is not classified as a Substance of Very High Concern (SVHC) and currently has no specific GHS classification requirements. However, it must comply with general chemical safety regulations, workplace exposure limits, and transportation regulations as a Class 8 corrosive substance under ADR.
