CAS 4045-44-7: Pentamethylcyclopentadiene

Description: Pentamethylcyclopentadiene, with the CAS number 4045-44-7, is an organic compound characterized by its unique structure, which features a cyclopentadiene core with five methyl groups attached. This compound is a derivative of cyclopentadiene, and its molecular formula reflects the presence of additional carbon and hydrogen atoms due to the methyl substitutions. Pentamethylcyclopentadiene is known for its high reactivity, particularly in coordination chemistry, where it can act as a ligand for transition metals. The presence of multiple methyl groups enhances its steric bulk and can influence its electronic properties, making it an interesting subject of study in organometallic chemistry. Additionally, this compound is typically a colorless liquid at room temperature and exhibits a distinctive odor. Its solubility in organic solvents and its relatively low boiling point make it suitable for various applications in chemical synthesis and research. Overall, pentamethylcyclopentadiene serves as a valuable building block in the development of more complex chemical entities.
