This organometallic compound is a specialized reagent in inorganic and materials chemistry, primarily used as a precursor for lead-selenium (PbSe) semiconductor nanocrystals and thin films. Its volatile and reactive nature enables controlled deposition in MOCVD (Metal–Organic Chemical Vapor Deposition) and solution-phase synthesis of PbSe quantum dots, which are critical for infrared photodetectors, solar cells, and optical communication devices. It also serves as a selenizing and lead-transfer reagent in organic synthesis, facilitating C–Se and C–Pb bond formation in complex molecule assembly. In academic research, it is employed to study the reactivity of organolead and organoselenium species, as well as for developing new catalytic systems involving main-group elements. Due to its high purity and well-defined stoichiometry, it is suitable for both small-scale laboratory synthesis and pilot-scale production of functional materials. Its compatibility with non-polar solvents makes it easy to handle under anhydrous, oxygen-free conditions.

This compound is a highly toxic organometallic substance with severe health and environmental hazards. Skin contact causes irritation, redness, and chemical burns; lead and selenium absorption can lead to systemic toxicity, including neurological damage and organ failure. Eye contact results in severe irritation, corneal injury, and potential vision loss; protective goggles or a face shield are mandatory. Inhalation of vapors or aerosols is extremely dangerous, causing respiratory tract irritation, headache, dizziness, and acute lead/selenium poisoning; use only in a fume hood with respiratory protection (N95 or higher). Ingestion is lethal in small amounts, causing gastrointestinal necrosis, organ damage, and death. It is non-flammable but decomposes at high temperatures, releasing toxic lead and selenium fumes. Store sealed under inert gas at 2–8 °C, away from oxidants, acids, and food. Wear full PPE: chemical-resistant gloves, lab coat, goggles, and respirator. Dispose of waste as hazardous material per local regulations; avoid environmental release—highly toxic to aquatic life.
