Bromooctadecane

1-Bromooctadecane_112-89-0_High Purity Stearyl Bromide_Surfactant Raw Material

Core Product Parameters:

1-Bromooctadecane, also known as stearyl bromide, CAS: 112-89-0, has the molecular formula C18H37Br and a molecular weight of 333.39. This product is a white to off-white waxy solid at room temperature (melting point 28-30°C) and is an important long-chain brominated alkane. Due to its unique eighteen-carbon chain structure, it exhibits excellent lipophilicity and surface activity, making it widely used as a raw material for surfactant synthesis and as a long-chain alkylating agent.

Specifications and Quality Control:

We provide high-purity 1-bromooctadecane products, with a standard specification of ≥98.0% (GC). Through strict quality control, our products feature low color, low moisture (≤500 ppm), low acid value, and low impurity content. Each batch undergoes multiple tests, including gas chromatography (GC) and Karl Fischer moisture determination, to ensure stable and reliable product quality that meets the needs of various application scenarios.

Main Application Areas:

1-Bromooctadecane is an important fine chemical intermediate, with key applications including:

Surfactant synthesis: Preparation of cationic surfactants (such as stearyltrimethylammonium bromide) and amphoteric surfactants

Phase transfer catalyst: Used in the synthesis of quaternary ammonium salt phase transfer catalysts

Functional materials: Serves as a precursor for preparing functional materials like ionic liquids and liquid crystal materials

Pharmaceutical intermediates: Used in synthesizing drug molecules with long-chain alkyl groups

Cosmetic ingredients: Employed in personal care products as raw materials for emulsifiers and emollients

Organic synthesis: Functions as a long-chain alkylating agent in various organic synthesis reactions

Textile auxiliaries: Used as raw materials for softeners and antistatic agents in textiles

Usage, Storage, and Safety Guidelines:
