3-methylbut-2-enal

3-methylbut-2-enal is an organic aldehyde compound with the molecular formula C5H8O and CAS number 107-86-8. This unsaturated aldehyde features a branched carbon chain with a methyl group at the third position and an aldehyde functional group. With a molecular weight of 84.12 g/mol, it belongs to the class of α,β-unsaturated aldehydes and is characterized by its reactive carbonyl group and double bond conjugation.

3-methylbut-2-enal is a colorless to pale yellow liquid at room temperature with a characteristic pungent, fruity odor. The compound has moderate volatility due to its relatively low molecular weight and contains both polar (carbonyl) and nonpolar (hydrocarbon) regions. It shows limited solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons due to its organic nature.

3-methylbut-2-enal serves primarily as an intermediate in organic synthesis and chemical manufacturing processes. Its reactive aldehyde group and conjugated double bond make it valuable for producing various chemical derivatives through condensation, addition, and polymerization reactions. The compound finds applications in pharmaceutical synthesis, fine chemical production, and as a building block for more complex organic molecules in specialized industrial processes.

Safe handling of 3-methylbut-2-enal requires standard chemical laboratory precautions including wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and lab coats. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation of vapors. Avoid contact with skin, eyes, and clothing, and ensure proper grounding when transferring the material to prevent static discharge.

3-methylbut-2-enal should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, ignition sources, and direct sunlight. Keep containers in secondary containment and away from incompatible materials such as strong oxidizers, acids, and bases. Storage areas should be equipped with appropriate spill control measures and maintained at stable temperatures to prevent degradation of the product.

In case of skin contact with 3-methylbut-2-enal, 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 and monitor breathing. In case of ingestion, do not induce vomiting and seek immediate medical attention.

3-methylbut-2-enal must be disposed of in accordance with local, national, and international waste regulations as a chemical waste. The material should not be discharged into drains, waterways, or the environment. Arrange disposal through licensed waste management companies specialized in chemical waste treatment. Small quantities may be suitable for incineration at appropriate facilities, while larger amounts require specialized chemical waste processing.

3-methylbut-2-enal is classified under ADR Class 8 (corrosive substances), Packing Group II, requiring specific packaging and labeling for transport. Containers must meet UN specification standards and display appropriate hazard labels and markings. Transportation should comply with ADR/RID regulations for road and rail transport, with proper documentation including safety data sheets and transport emergency cards accompanying shipments.

3-methylbut-2-enal is subject to standard chemical regulations including REACH registration requirements for manufacture, import, and use within the European Union. The substance is not classified as a Substance of Very High Concern (SVHC) and currently has no specific use restrictions under REACH Annex XVII. Handlers must comply with CLP regulation for classification, labeling, and packaging, along with standard occupational safety requirements.
