General description

1-Chlorooctadecane is a long-chain aliphatic compound that belongs to the class of alkyl halides. It is commonly used as a reagent in organic synthesis, particularly in the formation of alkyl chains in larger molecules. Its long hydrophobic alkyl chain makes it ideal for synthesis of surfactants, such as quaternary ammonium salts. The presence of the chlorine atom makes it susceptible to nucleophilic substitution reactions.
