Description

1,20-Dibromoeicosane is a high-purity, long-chain aliphatic dibromide compound, serving as a critical bifunctional alkylating agent and a versatile building block in organic synthesis. Its value lies in its ability to introduce a 20-carbon spacer with reactive bromine termini, enabling the construction of polymers, macrocycles, and complex molecular architectures. This product is essential for researchers and manufacturers in the pharmaceutical, polymer science, and advanced materials sectors, particularly for creating specialty surfactants, liquid crystals, and cross-linking agents.

Application

• Pharmaceutical Intermediate: Used in the synthesis of long-chain bioactive molecules, prodrugs, and lipid-based drug delivery systems.
• Polymer & Material Science: Acts as a monomer or chain extender for producing polyethers, polyesters, and specialty polymers with specific chain lengths.
• Macrocyclic Compound Synthesis: A key precursor for the preparation of large-ring compounds via cyclization reactions.
• Surface Chemistry & Surfactants: Serves as a hydrophobic linker for creating novel surfactants, phase-transfer catalysts, and surface-modifying agents.
• Liquid Crystal Production: Utilized as a mesogenic core or spacer in the manufacture of thermotropic liquid crystals for display technologies.
• Cross-linking Agent: Employed to introduce covalent cross-links into polymer networks to enhance mechanical and thermal properties.
• Organic Synthesis Building Block: Provides a reliable route to α,ω-difunctionalized eicosane derivatives for further chemical transformations.
