Cas no 6682-71-9 (1H-Indene,2,3-dihydro-4,7-dimethyl-)
1H-Indene,2,3-dihydro-4,7-dimethyl- is a substituted indene derivative characterized by a partially hydrogenated indene core with methyl groups at the 4 and 7 positions. This compound is of interest in organic synthesis and materials science due to its structural rigidity and potential as a building block for more complex molecules. Its saturated 2,3-dihydro moiety enhances stability while retaining reactivity for further functionalization. The methyl substitutions influence electronic properties, making it useful in the development of specialty chemicals, fragrances, or intermediates for pharmaceuticals. The compound’s defined structure and purity ensure consistent performance in research and industrial applications.
