Pentanal

Pentanal is an organic aldehyde compound with the molecular formula C5H10O and CAS number 110-62-3. It belongs to the family of aliphatic aldehydes, characterized by a five-carbon chain with a terminal aldehyde functional group (-CHO). With a molecular weight of 86.13 g/mol, pentanal appears as a colorless liquid with a characteristic pungent odor typical of aldehydes and is commonly used in chemical synthesis and fragrance applications.

Pentanal is a colorless liquid at room temperature with a strong, penetrating aldehyde odor. It has a boiling point of approximately 103°C and is moderately soluble in water while being miscible with most organic solvents like ethanol and ether. The compound is volatile and flammable, with a density lower than water. Its aldehyde functional group makes it reactive towards nucleophiles and oxidizing agents.

Pentanal is primarily used as an intermediate in organic synthesis for producing various chemicals including pharmaceuticals, flavoring agents, and fragrances. It serves as a building block in the manufacture of pentanoic acid, alcohols, and other aldehyde derivatives. The compound is also utilized in the production of rubber accelerators, plastic additives, and as a precursor in the synthesis of specialty chemicals for industrial applications.

Pentanal should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Keep away from heat sources, sparks, and open flames as the substance is flammable. Use non-sparking tools and ensure proper grounding when transferring the material to prevent static electricity buildup.

Pentanal should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Keep containers upright and protect from direct sunlight and temperature fluctuations. Store separately from strong oxidizing agents, acids, and bases to prevent unwanted reactions. Ensure storage areas are equipped with appropriate fire suppression systems and maintain temperatures below 25°C when possible.

In case of skin contact with pentanal, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush eyes with clean water for 15-20 minutes and seek medical attention. For inhalation exposure, move the person to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention while providing fresh air.

Pentanal must be disposed of according to local and national hazardous waste regulations as it is classified as flammable waste. Contact licensed waste disposal companies that handle organic chemical waste for proper collection and treatment. Small quantities may be incinerated at high temperatures in approved facilities. Never dispose of pentanal down drains, in soil, or with regular waste as it can harm the environment and violate environmental regulations.

Pentanal is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport protocols. It must be packaged in UN-approved containers with proper labeling and documentation. Transport vehicles must carry appropriate fire extinguishing equipment and emergency response information. Drivers need ADR certification for dangerous goods transport, and shipments must follow designated routes with proper placarding and emergency contact information readily available.

Pentanal is regulated under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) in Europe and must comply with CLP (Classification, Labelling and Packaging) regulations. It is not classified as a Substance of Very High Concern (SVHC). Companies using pentanal must maintain safety data sheets, conduct risk assessments, and implement appropriate risk management measures. Transport is governed by ADR regulations due to its flammable nature.
