  • Applications

    Metam, CAS 144-54-7, is primarily used as an intermediate in organic synthesis for industrial manufacturing; it may serve as a solvent or processing aid in polymer and plastic formulation; it can function as a stabilizer or plasticizer for certain polymers; it is used as a fragrance ingredient or fixative in perfumery and fragrance applications and may appear in cleaning products; in coatings, inks, and adhesives, it can be employed as a processing aid or additive, subject to local regulations and formulation limits.
