Description

11-(Bromomethyl)Henicosane is a high-purity, long-chain aliphatic bromoalkane, a versatile chemical intermediate for advanced organic synthesis. This compound is valued for its ability to introduce a functionalized C21 alkyl chain, enabling the creation of specialized surfactants, lubricant additives, and polymer modifiers. It is primarily sought by R&D chemists and process engineers in the fine chemical, pharmaceutical, and advanced materials industries for building complex molecular architectures.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel active pharmaceutical ingredients (APIs) and prodrugs requiring long hydrophobic chains.
• Specialty Surfactant & Emulsifier Precursor: Serves as a key building block for quaternary ammonium compounds (quats) and other cationic surfactants with unique surface-active properties.
• Lubricant & Fuel Additive Synthesis: Employed to create high-molecular-weight additives that improve viscosity index, reduce friction, or act as corrosion inhibitors.
• Polymer Modification Agent: Functions as an alkylating agent to introduce long side chains into polymers, altering physical properties like flexibility, hydrophobicity, or compatibility.
• Organic Synthesis Reagent: Acts as a reliable electrophile in nucleophilic substitution reactions (SN2) for C-alkylation in complex molecule construction.
• Material Science Research: Used in the development of self-assembled monolayers (SAMs), liquid crystals, and other functional organic materials.
