Comprehensive Guide to cis-b-Methylstyrene (Stablized with TBC) (CAS No. 766-90-5): Properties, Applications, and Industry Insights

cis-b-Methylstyrene (Stablized with TBC) (CAS No. 766-90-5) is a specialized organic compound widely utilized in industrial and research applications. This unsaturated hydrocarbon, stabilized with Tert-Butylcatechol (TBC), exhibits unique chemical properties that make it valuable for polymerization, adhesives, and specialty coatings. Its cis-configuration and methyl group positioning differentiate it from other styrene derivatives, offering tailored reactivity for niche applications.

The growing demand for high-performance monomers in the polymer industry has increased interest in CAS 766-90-5. Researchers and manufacturers frequently search for "cis-b-Methylstyrene uses," "TBC stabilization mechanism," or "766-90-5 solubility data," reflecting its technical relevance. Recent trends highlight its potential in low-VOC formulations, aligning with global sustainability initiatives. The compound's thermal stability and controlled polymerization characteristics make it suitable for advanced material science projects.

From a molecular perspective, 766-90-5 demonstrates distinct spectroscopic fingerprints (IR: 1630 cm-1 for C=C stretch; NMR: δ 5.2-5.8 ppm vinyl protons). Its stabilization with TBC (typically 10-100 ppm) prevents premature polymerization during storage, a critical feature for industrial users. Analytical methods like GC-MS and HPLC are commonly employed for purity verification (>98% typical commercial grade), addressing frequent queries about "cis-b-Methylstyrene analysis techniques."

In material applications, CAS 766-90-5 serves as a reactive diluent in epoxy systems and contributes to impact-resistant copolymers. Industry forums often discuss its "copolymerization with acrylates" or "crosslinking efficiency," particularly for automotive coatings. The compound's glass transition temperature (Tg) modulation capability makes it valuable for tuning polymer flexibility, a hot topic in 3D printing resins development.

Handling cis-b-Methylstyrene requires attention to its storage conditions (recommended: nitrogen atmosphere, <20°C) and inhibitor content monitoring.
