Chloroacetonitrile, identified by CAS number 107-14-2, is a chemical compound that demands rigorous attention to safety due to its inherent hazards. As a colorless, transparent liquid with a molecular formula of C2H2ClN, it is primarily utilized as an intermediate in organic synthesis, pharmaceuticals, and agrochemicals. However, its toxicological profile necessitates a comprehensive understanding of safe handling and storage practices.

The primary hazards associated with Chloroacetonitrile are clearly outlined by its GHS labeling: Danger. Key hazard statements include H301 (Toxic if swallowed), H311 (Toxic in contact with skin), H331 (Toxic if inhaled), and H411 (Toxic to aquatic life with long lasting effects). These statements underscore the critical need for protective measures to prevent exposure.

Recommended precautionary measures are extensive and must be followed diligently. This includes keeping the compound away from heat, hot surfaces, sparks, open flames, and other ignition sources, with a strict prohibition on smoking in its vicinity (P210). Avoiding release into the environment is also crucial (P273). When handling, it is imperative to wear protective gloves, clothing, eye protection, and face protection, along with hearing protection if necessary (P280).

In case of exposure, immediate action is required. If swallowed, call a POISON CENTER/doctor immediately (P301+P310). If on skin (or hair), take off all contaminated clothing immediately and rinse skin with water (P302+P353). If inhaled, remove the person to fresh air and keep them comfortable for breathing, then call a POISON CENTER/doctor (P304+P340+P311). It is also advised to rinse mouth (P330) and wash contaminated clothing before reuse (P363).

Proper storage is equally important for maintaining safety and product integrity. Chloroacetonitrile should be stored in a well-ventilated place and kept cool. The storage class is designated as 3 for flammable liquids, and it is categorized as highly hazardous to water. Disposal should be handled with extreme care, adhering to regulations for carcinogenic and flammable compounds labeled as highly toxic or toxic.

The physical properties of Chloroacetonitrile, such as its flash point of 118°F and density of 1.193 g/cm³, are critical considerations for safe storage and handling. Its appearance as a liquid and its specific boiling point (124-126°C) also inform the necessary precautions. By adhering to these guidelines, professionals can mitigate risks and ensure the safe and effective utilization of Chloroacetonitrile in their respective fields.
