Pentanedial

Pentanedial is an organic chemical compound with the molecular formula C5H8O2 and CAS number 111-30-8. This dialdehyde has a molecular weight of 100.12 g/mol and belongs to the aldehyde family of compounds. It is classified as a hazardous substance with multiple danger classifications including acute toxicity, skin corrosion, and respiratory sensitization properties, requiring careful handling in industrial applications.

Pentanedial is a liquid organic compound at room temperature with two aldehyde functional groups. As a dialdehyde, it typically exhibits high reactivity due to its dual carbonyl groups. The compound has a molecular weight of 100.12 g/mol and contains five carbon atoms in its chain structure. Its chemical properties make it highly reactive with nucleophiles and prone to polymerization reactions.

Pentanedial is primarily used as a disinfectant and sterilizing agent in healthcare and industrial applications. It serves as a cross-linking agent in various chemical processes and is utilized in the preservation of biological specimens. The compound is also employed in water treatment systems and as an antimicrobial agent in various industrial formulations due to its biocidal properties.

Pentanedial requires strict safety measures due to its corrosive and toxic properties. Personal protective equipment must include chemical-resistant gloves, safety goggles, and respiratory protection to prevent inhalation. Work should be conducted in well-ventilated areas or under fume hoods. Avoid skin and eye contact, and ensure emergency eyewash stations and safety showers are readily accessible during handling operations.

Pentanedial must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly sealed and protected from light to prevent degradation. Storage areas should be equipped with appropriate spill containment measures and emergency equipment. Ensure proper segregation from oxidizing agents, bases, and other reactive chemicals to prevent dangerous reactions.

Immediate action is required for pentanedial exposure due to its corrosive nature. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move to fresh air immediately. Always seek professional medical advice after any exposure incident.

Pentanedial disposal must comply with local and international hazardous waste regulations due to its toxic and corrosive properties. The substance cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment facilities. Contact licensed waste disposal companies for proper collection and treatment. Neutralization may be possible under controlled conditions by qualified professionals before final disposal.

Pentanedial is classified under ADR Class 8 (corrosive substances) with Packing Group II, indicating significant transport hazards. Shipments must use appropriate UN-specification packaging and display proper hazard labels including corrosive substance markings. Transport vehicles require specific equipment and trained personnel familiar with dangerous goods regulations. All transport documentation must comply with ADR requirements for corrosive materials.

Pentanedial is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification obligations. The substance carries multiple hazard classifications requiring specific labeling with GHS pictograms (GHS06, GHS05, GHS08, GHS09) and danger signal words. Industrial users must implement appropriate risk management measures and ensure compliance with occupational exposure limits and safety data sheet requirements.

Pentanedial is available through OYSI, a specialized European distributor of technical chemicals serving industrial customers across the continent. As a hazardous substance requiring expert handling, purchasing should only be done through qualified chemical distributors who can provide proper documentation, safety data sheets, and technical support. Professional suppliers ensure compliance with European chemical regulations and safe delivery practices.
