Crotyl mercaptan is a sulfur-containing thiol with a crotyl group and a thiol (-SH) functionality. In the fragrance industry, it may be considered an odorant or fragrance ingredient, given the characteristic notes of thiol compounds. In polymer and materials chemistry, it is commonly used as a synthetic intermediate to access sulfur-containing compounds and to participate in thiol-ene reactions, serving as a crosslinking or reactive component in UV-curable coatings, adhesives, and specialty polymers. Due to the thiol group’s affinity for metals, crotyl mercaptan can be employed for surface modification of metal substrates and for forming self-assembled monolayers (SAMs) to tailor surface properties for electronics or coating applications. These applications depend on local regulations and formulation limits.
