Trichloroacetonitrile CAS 545-06-2

1. Trichloroacetonitrile CAS 545-06-2 is widely used as a key reagent in the Overman rearrangement for synthesizing allylic amines from allylic alcohols, and in the preparation of trichloroacetimidates, which are important intermediates for further transformations. Trichloroacetonitrile CAS 545-06-2 is also used to prepare bistrichloroacetimidates from diols, leading to dihydrooxazines through acid-catalyzed cyclization.
2. The compound serves as an important intermediate in pharmaceutical synthesis, pesticide formulation, and the production of specialty polymers. It is also employed in analytical chemistry for detecting and quantifying other chemical compounds.
3. Applications of Trichloroacetonitrile also include its use in organic synthesis as a valuable reagent for facilitating the synthesis of complex organic molecules and improving reaction yields.

1. Store Trichloroacetonitrile CAS 545-06-2 in a tightly sealed container in a cool, dry, and well-ventilated place. Recommended storage temperatures vary: room temperature, 20°C, 2-8°C (refrigerated), or ambient temperatures. It should be protected from moisture and kept in a cool, dark place.
2. Keep Trichloroacetonitrile strictly away from strong oxidizing agents, strong acids, strong bases, and strong reducing agents, as contact may cause hazardous reactions. Trichloroacetonitrile is also incompatible with water and moisture.
3. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves, tightly fitting safety goggles or face shield, and protective clothing. Handle only with adequate ventilation or in a chemical fume hood, and avoid breathing vapors, mist, or gas. Use in areas with good industrial hygiene and safety practice, and wash hands thoroughly after handling.

1. Immediately isolate the spill area, evacuate non-essential personnel, eliminate all ignition sources, and ensure adequate ventilation. Use personal protective equipment and do NOT let Trichloroacetonitrile CAS 545-06-2 enter drains or waterways.
2. Contain Trichloroacetonitrile using inert, non-combustible absorbent material (e.g., dry sand, vermiculite). Carefully collect the contaminated material using spark-proof tools into a sealed, labeled chemical waste container for proper disposal according to hazardous material regulations.
3. Personnel Trichloroacetonitrile must wear suitable PPE including self-contained breathing apparatus (SCBA) during cleanup. Under fire conditions, decomposition products include carbon oxides, nitrogen oxides, and hydrogen chloride. Use dry chemical, carbon dioxide, or alcohol-resistant foam as extinguishing media; water may be ineffective. Trichloroacetonitrile is classified for transport.

1. Trichloroacetonitrile CAS 545-06-2 is classified with GHS signal word "Danger". It is toxic if swallowed (H301), in contact with skin (H311), and if inhaled (H331). Acute toxicity data shows oral LD50 of 250 mg/kg in rats and dermal LD50 of 900 mg/kg in rabbits. It is also toxic to aquatic life with long-lasting effects (H411).
2. Trichloroacetonitrile is a combustible liquid that reacts with water, releasing toxic and flammable gases. Its thermal decomposition produces toxic and irritating fumes including carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen chloride, and cyanide gases. It is incompatible with strong oxidizing agents, acids, bases, and reducing agents. Vapors are heavier than air and may form explosive mixtures with air. Environmental toxicity data includes reproductive effects in rats (cardiovascular and urogenital abnormalities).
3. Always Trichloroacetonitrile consult the specific Safety Data Sheet (SDS) for Trichloroacetonitrile for complete hazard information, first-aid procedures, and handling instructions. Precautionary statements include P260 (do not breathe vapors), P273 (avoid release to environment), P280 (wear protective gloves/eye protection), and P311 (call a poison center/doctor).
