Description

Application

• 1-Octadecanol is used in the synthesis of O-octadecyl-S-trifluorothiolcarbonate, which is a storable crystalline source of trifluoromethanethiol.
• It can be used to improve solution processability of conjugated polymers used in the organic electronic applications.
• It induces hydrophobicity to the amphiphiles used in the drug and gene delivery.
• It is also employed in the synthesis of solid-liquid phase change materials (PCMs), surfactant and stabilizers.
