Diethyl Azodicarboxylate CAS 1972-28-7

1. Diethyl azodicarboxylate (DEAD) is primarily used as a key reagent in the Mitsunobu reaction for esterification, etherification, and amination of alcohols.
2. Diethyl azodicarboxylate CAS 1972-28-7 serves as a versatile dehydrogenating agent and dienophile in Diels-Alder and other cycloaddition reactions.
3. This compound is also utilized in the synthesis of heterocycles, pharmaceuticals, and natural products.

1. Store diethyl azodicarboxylate under refrigeration (e.g., 2-8°C) in a tightly sealed, original container, away from heat, sparks, and open flames. **Store separately and away from any reducing agents, phosphines, or other highly reactive compounds to avoid violent reactions.**
2. Keep the container in a well-ventilated, fire-resistant area, clearly labeled. Diethyl azodicarboxylate CAS 1972-28-7 is often supplied as a solution (e.g., in toluene) to reduce hazard.
3. Handle with extreme caution using appropriate personal protective equipment (PPE): chemical-resistant gloves, safety goggles, face shield, and a lab coat. Always use a fume hood and consider blast shielding for larger quantities.

1. Immediately evacuate and isolate the area. Do not touch spilled material. Alert trained personnel. Wear full protective gear (gloves, goggles, protective clothing, respirator).
2. **Do not use combustible materials (e.g., paper, sawdust) for cleanup.** For small spills, carefully absorb with an inert, non-combustible material (e.g., sand, vermiculite). Place all contaminated material in a sealed, labeled container for hazardous waste disposal. Keep material wet with a compatible solvent if possible.
3. Prevent Diethyl azodicarboxylate CAS 1972-28-7 from entering drains, sewers, or the environment. Decontaminate tools and surfaces with a suitable solvent, following all regulations. Large spills require expert assistance.

1. Diethyl azodicarboxylate is **highly toxic** if swallowed, inhaled, or absorbed through the skin. Diethyl azodicarboxylate CAS 1972-28-7 causes severe skin burns, eye damage, and respiratory damage. It is a suspected carcinogen and mutagen.
2. Diethyl azodicarboxylate CAS 1972-28-7 is **extremely flammable** and a severe explosion hazard. It is shock-sensitive, heat-sensitive, and can decompose violently, especially when pure, dry, or in contact with incompatible substances (phosphines, reducing agents). It may emit toxic fumes (nitrogen oxides, carbon oxides) when heated.
3. **Always consult the official diethyl azodicarboxylate Safety Data Sheet (SDS) and handle it as a high-risk explosive, flammable, and toxic material.** Specialized training and procedures are required. Never use or store near incompatible chemicals.
