Isotridecyl, Isotridecane-1-ol 27458-92-0

Isotridecanol (C₁₃H₂₈O)

Tridecanol isomer is a branched-chain primary alcohol containing 13 carbon atoms, composed of multiple isomers (the main components are trimethyldecanol and tetramemethylnonanol, etc.). Due to its branched structure, it has a lower freezing point and better solubility than straight-chain tridecanol, and is widely used in fields such as surfactants, lubricating oil additives, and plasticizers.
