Lead Tetraacetate, with the CAS number 546-67-8, is a chemical compound known for its high - quality properties and is offered at the best price in the market. Its molecular formula is C₈H₁₂O₈Pb. It appears as white or colorless crystals. The molar mass of Lead Tetraacetate is approximately 443.38 g/mol. It is soluble in glacial acetic acid and other organic solvents such as benzene, chloroform, and carbon tetrachloride. However, it is sensitive to moisture and should be stored in a dry and cool place, away from light and oxidizing agents.
1. **Oxidizing Agent**: Lead Tetraacetate is a powerful oxidizing agent in organic synthesis. It can be used to oxidize various functional groups. For example, it can convert alcohols to aldehydes or ketones under appropriate reaction conditions. It can also oxidize glycols to carbonyl compounds through oxidative cleavage reactions.
2. **Synthetic Intermediate**: In the pharmaceutical and fine - chemical industries, it serves as an important synthetic intermediate. It can be used in the synthesis of complex organic molecules, including some natural products and drug candidates. For instance, it can be used in the construction of specific carbon - carbon and carbon - oxygen bonds in the synthesis of bioactive compounds.
3. **Research and Development**: In academic and industrial research laboratories, it is widely used in research projects related to organic chemistry. Scientists use it to explore new reaction mechanisms and develop novel synthetic methods.
1. **Handling Precautions**: When handling Lead Tetraacetate, it is essential to wear appropriate personal protective equipment, including gloves, safety goggles, and a lab coat. Since it is a toxic and moisture - sensitive compound, all operations should be carried out in a well - ventilated fume hood.
2. **Reaction Setup**: Dissolve the required amount of Lead Tetraacetate in a suitable organic solvent, such as glacial acetic acid or benzene, under anhydrous conditions. Add the substrate slowly to the solution while stirring continuously. The reaction temperature and time should be carefully controlled according to the specific reaction requirements. After the reaction is complete, the product can be isolated and purified by standard organic separation techniques, such as extraction, filtration, and distillation.
1. **Synthesis of a Pharmaceutical Intermediate**: A pharmaceutical company was working on the synthesis of a new anti - inflammatory drug. They used Lead Tetraacetate as an oxidizing agent to convert a key intermediate alcohol to the corresponding aldehyde. The reaction was carried out in glacial acetic acid at a temperature of 50°C for 2 hours. After purification by column chromatography, they obtained the desired aldehyde with a yield of 80%. This step was crucial in the overall synthesis of the drug, as it set the stage for further reactions to form the final bioactive compound.
2. **Research on Oxidative Cleavage of Glycols**: In an academic research project, a team of chemists was studying the oxidative cleavage of glycols using Lead Tetraacetate. They investigated different reaction conditions, such as solvent type, temperature, and reaction time. By using Lead Tetraacetate in benzene at room temperature for 3 hours, they were able to achieve a high - efficiency cleavage of the glycols, producing the corresponding carbonyl compounds in good yields. This research provided new insights into the reaction mechanism of oxidative cleavage reactions.
