  • Applications

    Lysine thiazolidine carboxylate (CAS 57762-37-5) is an amino‑acid‑derived compound commonly used as an intermediate in chemical synthesis and as a building block for pharmaceutical and specialty chemicals. It may serve as a reactive precursor for polymers and plastics, acting as a monomer or co‑monomer in systems such as polyamides and polyurethanes. In coatings and inks, it can function as a stabilizer or crosslinking component to improve film properties. In cosmetics/personal care, it has been evaluated as a functional ingredient in formulations. In cleaning formulations and metal‑processing applications, it can act as a chelating agent or pH‑adjusting additive, depending on the formulation.
