Benzaldehyde

Benzaldehyde is an aromatic aldehyde compound with the molecular formula C7H6O and CAS number 100-52-7. It has a molecular weight of 106.12 g/mol and appears as a colorless liquid with a characteristic bitter almond odor. This organic compound is classified as Acute Tox. 4 under the GHS system and carries the warning signal word with GHS07 pictogram, indicating moderate toxicity concerns that require appropriate handling precautions.

Benzaldehyde is a colorless to pale yellow liquid at room temperature with a distinctive sweet, bitter almond-like odor. It has a molecular weight of 106.12 g/mol and the chemical formula C7H6O. The compound is slightly soluble in water but readily soluble in organic solvents such as ethanol, ether, and benzene. It has a boiling point of approximately 179°C and a density of about 1.04 g/cm³ at 20°C.

Benzaldehyde is primarily used as a flavoring agent in food products, particularly for almond flavoring in baked goods, desserts, and beverages. In the chemical industry, it serves as an important intermediate for the synthesis of pharmaceuticals, dyes, and perfumes. It is also used in the production of benzyl alcohol, benzoic acid, and various organic compounds. Additionally, benzaldehyde finds applications in the manufacture of plasticizers and as a solvent in certain industrial processes.

Benzaldehyde requires careful handling due to its Acute Tox. 4 classification and GHS07 warning pictogram. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent inhalation of vapors. Avoid direct skin and eye contact, and prevent ingestion. Work in well-ventilated areas or under fume hoods when possible. Keep away from heat sources, sparks, and open flames as a precautionary measure.

Benzaldehyde should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers upright and protected from physical damage. Store away from strong oxidizing agents, acids, and bases to prevent incompatible reactions. Maintain storage temperatures below 25°C when possible and ensure proper labeling according to GHS requirements. Use appropriate secondary containment measures and ensure storage areas comply with local fire safety regulations.

Benzaldehyde contact requires immediate first aid measures. For skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. If swallowed, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist or worsen.

Benzaldehyde disposal must comply with local, national, and EU waste regulations. The substance should be treated as hazardous waste and disposed of through licensed waste management facilities. Do not pour down drains, sewers, or onto the ground. Small quantities may be suitable for incineration at authorized facilities with appropriate emission controls. Always consult with certified waste disposal companies and follow the waste classification codes according to the European Waste Catalogue for proper disposal documentation.

Benzaldehyde is classified under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III, indicating it requires specific transport regulations. Packages must be properly labeled and marked according to ADR requirements. Use appropriate packaging that meets UN specification standards for Class 9 materials. Transport vehicles should carry proper documentation including transport documents and emergency response information. Ensure drivers are trained in hazardous materials transport and emergency procedures according to European transport regulations.

Benzaldehyde is subject to various European regulations including REACH registration requirements and CLP classification obligations. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH. The substance must be classified and labeled according to the CLP Regulation as Acute Tox. 4 with appropriate warning pictograms. Food-grade benzaldehyde used as flavoring agent is also regulated under EU food additive legislation. Always ensure compliance with current regulatory requirements and safety data sheet provisions.
