  • Applications

    2,4-Dichlorobenzyl alcohol (CAS 1777-82-8) is primarily used as an intermediate in the synthesis of fragrance ingredients and other specialty chemicals. In perfumery and cosmetics, it functions as a fragrance intermediate and can serve as an odorant or fixative for specific notes. It also serves as an intermediate in the manufacture of dyes, agrochemicals, and pharmaceutical intermediates, providing a building block for various industrial chemicals. Additionally, it may be used as a reactive intermediate or component in coatings and inks formulations in some industrial applications, while household fragrance products may contain it as an ingredient subject to local regulations.
