  • Applications

    Raphasatin (CAS 13028-50-7) is a reactive isothiocyanate with a pungent, radish-like aroma. It is considered for use as an odorant in fragrance applications and as a flavor note, and can serve as an intermediate in the synthesis of sulfur-containing compounds for specialty chemicals. In research contexts, isothiocyanates of this type are evaluated for biological activity that informs agrochemical development, including antimicrobial or herbicidal properties. In cosmetics and personal care formulations, it may be contemplated as a fragrance ingredient under regulatory controls. Use and handling are subject to local regulations and formulation limits.
