(1R,2S,4S,5R)-cyclohexane-1,2,4,5-tetracarboxylic dianhydride CAS 1198787-91-5 - 99% Min. White Powder - Kharagpur

(1R,2S,4S,5R)-cyclohexane-1,2,4,5-tetracarboxylic dianhydride (CAS 1198787-91-5) is a specialized cycloaliphatic dianhydride used as a monomer and functional building block in high-performance polymer research. Its defined stereochemical configuration and rigid cyclohexane-based structure make it particularly valuable for the development of advanced polyimide and other functional polymer systems.

Compared with conventional aromatic dianhydrides, cycloaliphatic dianhydrides can offer advantages such as improved optical transparency, lower coloration, and favorable dielectric characteristics. These properties have increased interest in their use for next-generation electronic and optical materials.

The compound contains two anhydride functionalities that can readily participate in polycondensation with suitable diamine monomers, enabling the preparation of specialized polyimide materials. Potential research areas include colorless polyimides, optoelectronic materials, flexible displays, optical films, semiconductor-related materials, and high-performance polymer systems.
