Product Parameters
1-Bromooctadecane (Stearyl Bromide,Octadecyl Bromide) CAS No.: 112-89-0,Molecular formula: C18H37Br, M.W.: 333.39, is a white to light yellow solid. It is an important long-chain brominated alkane. Due to its eighteen-carbon-chain structure, it exhibits excellent lipophilicity and surface activity, and is widely used as a raw material for surfactant synthesis and as a long-chain alkylating reagent.
Specifications & Quality Control
We provide high-purity Bromooctadecane with a standard specification of ≥ 98.0% (GC). Through strict quality control, the product has the characteristics of low color (APHA), low moisture (determined by Karl Fischer method), low acid value, and low impurity content. Each batch of products undergoes multiple tests, including gas chromatography (GC) and Karl Fischer moisture determination, to ensure stable and reliable quality that meets the requirements of various application scenarios.
Main Applications
1-Bromooctadecane is an important fine chemical intermediate with a wide range of applications, including:
Surfactant Synthesis:
Production of cationic surfactants (e.g., octadecyltrimethylammonium bromide) and amphoteric surfactants.
Phase-Transfer Catalysis:
Utilized in the synthesis of quaternary ammonium salt phase-transfer catalysts.
Functional Materials:
Serving as a precursor for the preparation of ionic liquids, liquid-crystalline materials, and other advanced functional materials.
Pharmaceutical Intermediates:
Applied in the synthesis of drug molecules featuring long-chain alkyl groups.
Cosmetic raw materials:
