Indene (CAS 95-13-6) is a fascinating aromatic hydrocarbon that commands attention due to its unique chemical structure and diverse industrial applicability. Possessing a bicyclic framework composed of a benzene ring fused to a cyclopentene ring, Indene exhibits a reactivity profile that makes it a valuable intermediate and solvent in various chemical processes. Understanding the fundamental indene chemical properties is key to unlocking its full industrial potential.

Physically, Indene is described as a colorless to pale yellow transparent liquid. Its molecular formula is C9H8, with a molecular weight of approximately 116.16 g/mol. Key physical properties include a boiling point around 181-182°C and a density close to 0.996 g/ml at 25°C. These characteristics are important considerations for its handling, storage, and use in industrial settings. For instance, its relatively high boiling point influences its suitability as a solvent in applications requiring moderate volatility.

The reactivity of Indene stems from its conjugated double bond system within the five-membered ring, making it susceptible to various chemical transformations. It readily undergoes polymerization, a property crucial for its use in creating coumarone-indene resins. This polymerization can be initiated under the influence of catalysts such as aluminum chloride or sulfuric acid. Beyond polymerization, Indene can also participate in reactions like Diels-Alder cycloadditions, which are fundamental in synthesizing complex organic molecules and are explored in advanced materials science.

The industrial significance of Indene is further amplified by its role as a chemical intermediate. It serves as a precursor for producing synthetic resins, which are widely employed in paints, coatings, and adhesives due to their durability and resistance properties. Moreover, Indene is used in the synthesis of insecticides, contributing to the agricultural chemical sector. The availability of specific grades, such as Indene CAS 95-13-6 with high purity, is essential for these specialized manufacturing processes.
