  • Applications

    N,N'-Bis(1-oxooctyl)-L-cystine, CAS 41760-23-0, is a diacylated cystine derivative that can function as a chemical intermediate and a lipophilic modifier in specialized formulations. In polymers/plastics, it may serve as a building block or a crosslinking/compatibilizing agent for advanced systems. In coatings and inks, it can act as an additive influencing adhesion, compatibility, or cure behavior. In adhesives, it may participate as a coupling or formulation-modifying ingredient. In cosmetics/personal care, it could be used as a lipophilic modifier or conditioning-agent precursor for emulsions and creams. In industrial manufacturing, it may be evaluated as an intermediate in complex organic syntheses and as a niche additive to tailor properties. Use is subject to local regulations and formulation limits.
