2,6-dichlorobenzonitrile

2,6-dichlorobenzonitrile is an aromatic organic compound with the molecular formula C7H3Cl2N and CAS number 1194-65-6. This chemical features a benzene ring substituted with two chlorine atoms at positions 2 and 6, and a nitrile group (-CN). With a molecular weight of 172.01 g/mol, it belongs to the family of chlorinated benzonitriles and is classified as a moderately hazardous substance requiring careful handling procedures.

2,6-dichlorobenzonitrile is typically a white to off-white crystalline solid at room temperature with a characteristic aromatic odor. The compound exhibits limited water solubility due to its chlorinated aromatic structure but shows good solubility in organic solvents such as acetone, ethanol, and chlorinated solvents. Its stability is generally good under normal conditions, though it should be protected from strong bases and reducing agents that could affect the nitrile group.

2,6-dichlorobenzonitrile is primarily used as an intermediate in pharmaceutical synthesis and agrochemical manufacturing. It serves as a key building block for producing various herbicides, fungicides, and pharmaceutical compounds. The compound is also utilized in organic synthesis research and chemical manufacturing processes where chlorinated aromatic intermediates are required. Its specific substitution pattern makes it valuable for creating molecules with desired biological or chemical properties.

2,6-dichlorobenzonitrile requires standard chemical safety precautions including wearing protective gloves, safety goggles, and lab coats to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation. The substance is classified as Acute Tox. 4, requiring careful handling to prevent accidental exposure. Avoid eating, drinking, or smoking when handling the material, and wash hands thoroughly after use.

2,6-dichlorobenzonitrile should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed and store in original packaging or compatible chemical-resistant containers. Separate from strong acids, bases, oxidizing agents, and reducing materials to prevent unwanted reactions. Ensure storage areas are equipped with appropriate spill containment measures and maintain proper inventory control to monitor container integrity and expiration dates.

In case of skin contact with 2,6-dichlorobenzonitrile, 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 minutes while holding eyelids open. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms develop or persist after exposure.

2,6-dichlorobenzonitrile waste must be disposed of in accordance with local, national, and EU waste regulations as a hazardous chemical waste. The substance cannot be disposed of in regular trash or sewage systems due to its toxicity and environmental persistence (Aquatic Chronic 2 classification). Contact licensed hazardous waste disposal companies for proper collection and treatment. Small laboratory quantities may require special packaging and labeling before disposal through institutional waste management programs.

2,6-dichlorobenzonitrile is classified under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. This classification indicates it requires proper packaging, labeling, and documentation during transport but represents a lower degree of danger during transport. Packages must bear appropriate hazard labels and be accompanied by transport documents. Drivers must have appropriate training and vehicles should carry emergency response information and protective equipment as required by ADR regulations.

2,6-dichlorobenzonitrile is subject to European REACH regulation requiring registration for manufacture or import above certain tonnages. Under CLP regulation, it must be classified and labeled with GHS07 and GHS09 pictograms and 'Warning' signal word. The substance is not currently listed as SVHC (Substance of Very High Concern) but its Aquatic Chronic 2 classification means it requires environmental risk assessment. Industrial users must comply with occupational exposure limits and environmental discharge restrictions.
