2-chlorobenzaldehyde

2-chlorobenzaldehyde is an aromatic aldehyde compound with the molecular formula C7H5ClO and CAS number 89-98-5. This organic chemical features a benzene ring substituted with both a chlorine atom and an aldehyde functional group in the ortho position. With a molecular weight of 140.56 g/mol, it is classified as a corrosive substance (Skin Corr. 1B) requiring careful handling due to its hazardous properties.

2-chlorobenzaldehyde is typically a colorless to pale yellow liquid at room temperature with a characteristic aldehyde odor. As an aromatic compound, it has moderate polarity due to the aldehyde group and is generally soluble in organic solvents like ethanol and acetone but has limited solubility in water. The presence of the chlorine substituent influences its reactivity and physical properties compared to unsubstituted benzaldehyde.

2-chlorobenzaldehyde serves as an important intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used in the production of various chemical compounds including dyes, agrochemicals, and pharmaceutical intermediates. The compound's aldehyde functionality and chlorine substitution make it valuable for further chemical transformations in industrial processes, particularly in the synthesis of more complex aromatic compounds and specialty chemicals.

2-chlorobenzaldehyde requires strict safety measures due to its corrosive classification (Skin Corr. 1B). Personnel must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Handle containers carefully to avoid spills and ensure emergency shower and eyewash facilities are readily accessible.

2-chlorobenzaldehyde should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. As a corrosive substance, it requires storage in appropriate chemical-resistant containers and secondary containment. Keep away from oxidizing agents, strong bases, and reducing agents. Storage areas should be equipped with appropriate spill control measures and clearly labeled with hazard warnings.

Immediate action is critical due to the corrosive nature of 2-chlorobenzaldehyde. For skin contact, immediately remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse immediately with water for at least 15 minutes and seek medical attention promptly. If inhaled, move the person to fresh air immediately. Always seek medical attention for any exposure incident.

2-chlorobenzaldehyde disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance should never be poured down drains or disposed of with regular waste. Contact authorized hazardous waste disposal companies for proper collection and treatment. Small quantities may require neutralization or incineration at licensed facilities. Always consult local environmental authorities for specific disposal requirements in your region.

2-chlorobenzaldehyde is classified under ADR Class 8 (corrosive substances), Packing Group III for transportation purposes. It must be packaged in appropriate UN-specification containers and labeled with the correct hazard labels including the GHS05 pictogram. Transportation requires proper documentation including safety data sheets and transport documents. Only authorized carriers experienced in handling corrosive chemicals should transport this substance.

2-chlorobenzaldehyde is subject to European chemical regulations including REACH and CLP classification requirements. It is classified as Skin Corr. 1B with the signal word 'Danger' and requires appropriate hazard communication. The substance is not currently listed as a Substance of Very High Concern (SVHC). Companies handling this chemical must ensure compliance with occupational safety regulations and proper worker protection measures.
