  • Applications

    Sodium cyclopentane carboxylate is primarily used as an organic synthesis intermediate and building block for cyclopentyl-containing compounds; it may be employed in fragrance chemistry as a precursor to cyclopentyl odorants; it can serve as a processing aid or precursor in polymer and plastics manufacturing to access cyclopentyl-containing monomers or additives; in cosmetics and personal care products it is sometimes used as a formulation component to adjust pH or modify ionic strength; in coatings, inks and cleaning formulations it can act as a salt that helps tailor formulation properties such as solubility and rheology.
