Description

16-Chlorohexadeca-5,9-diyne is a high-purity, synthetic aliphatic compound featuring a terminal chloro group and two strategically positioned internal alkyne functionalities. This unique molecular architecture makes it a versatile and valuable chemical building block for advanced organic synthesis and materials science research. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular scaffolds and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for creating long-chain hydrocarbon spacers or as a precursor for click chemistry applications.
• Agrochemical Research: Used in developing new crop protection agents, where its alkyne groups allow for modular derivatization to optimize biological activity.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for producing specialty polymers with tailored properties, such as polyacetylenes or networks with specific rigidity and functionality.
• Chemical Biology Probes: Employed in the synthesis of molecular probes and tags via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or other alkyne-based bioconjugation techniques.
• Liquid Crystal & OLED Materials: Functions as a precursor for synthesizing advanced organic electronic materials and liquid crystal compounds requiring specific linear, rigid backbones.
• Surface Modification: Used to create self-assembled monolayers (SAMs) or to functionalize surfaces with long-chain, reactive groups for further chemical grafting.
