Product Name:1-Bromooctadecane
English Name:1-Bromooctadecane
CAS No.:112-89-0
Aliases:Stearyl bromide, Octadecyl bromide, n-Octadecyl bromide
Molecular Formula:C18H37Br
Physical Properties:Molecular weight: 333.39. White to slightly yellow waxy solid at room temperature; melting point 28~30°C; boiling point 374°C (at atmospheric pressure), 210~215°C/0.67kPa (reduced pressure); density 0.98 g/cm³ (25°C, liquid); refractive index nD30=1.4630~1.4650. Insoluble in water, readily soluble in most organic solvents such as ethanol, diethyl ether, acetone, benzene and petroleum ether; good compatibility with aliphatic hydrocarbons, aromatic solvents and oils. Stable under sealed storage at room temperature; avoid contact with strong oxidants and strong bases.
Uses:Used as an organic synthesis intermediate. As a very long-chain alkylating reagent, it introduces an octadecyl chain into target molecules via nucleophilic substitution of the bromine atom, serving as an important raw material for the synthesis of long-chain aliphatic compounds, cationic surfactants, lubricant additives and waterproofing agents. It can also be used to prepare long-chain aliphatic derivatives such as octadecanol and octadecylamine, and as a standard substance for the development of chromatographic analytical methods.
