Description

1-Bromooctadecane is a high-purity, long-chain alkyl bromide, also known as octadecyl bromide. This versatile organic intermediate is valued for its role in introducing the octadecyl (C18) group into target molecules, enabling the synthesis of surfactants, phase-transfer catalysts, and specialty polymers. It is a critical raw material for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to modify surface properties or create novel functional compounds.

Application

• Surfactant & Quaternary Ammonium Salt Synthesis: A key alkylating agent for producing cationic surfactants like distearyldimonium chloride and other fabric softeners, antistatic agents, and biocides.
• Phase-Transfer Catalyst (PTC) Production: Used to manufacture quaternary ammonium salts that serve as efficient phase-transfer catalysts in biphasic organic reactions.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of active pharmaceutical ingredients (APIs) and lipid-based drug delivery systems.
• Polymer Modification & Additives: Employed to alkylate polymers or create polymerizable monomers, leading to materials with specific hydrophobic or self-assembling properties.
• Agrochemical Intermediates: Used in the synthesis of certain pesticides and plant growth regulators that require long alkyl chains.
• Research & Development: A valuable reagent in organic synthesis laboratories for nucleophilic substitution reactions and material science research.
• Lubricant & Fuel Additives: Acts as a precursor for additives that improve viscosity index or provide anti-wear properties.
