Description

Cyclohexane, 1,3-Diethynyl-, trans- (9Ci) is a specialized organic compound featuring a cyclohexane ring substituted with two ethynyl groups in a trans configuration. This compound is valued as a high-purity building block and advanced intermediate in synthetic organic chemistry and materials science research. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for creating constrained, three-dimensional structures.
• Agrochemical Research: Used in the development of new crop protection agents and herbicides where its rigid, alkyne-functionalized core can impart unique biological activity.
• Advanced Material Precursor: Acts as a monomer or cross-linking agent in the development of specialty polymers, resins, and metal-organic frameworks (MOFs) with tailored properties.
• Organic Synthesis Building Block: Employed in click chemistry (e.g., Huisgen cycloaddition), Sonogashira coupling, and other catalytic transformations to introduce alkyne functionality.
• Ligand Synthesis: Utilized for creating novel ligands for catalysis and coordination chemistry due to the presence of multiple reactive sites.
• Academic & Industrial R&D: A critical reagent for exploratory chemistry in universities and corporate research centers focused on drug discovery and functional materials.
