  • Applications

    Butyl 2-hydroxybenzene-1-carboperoxoate (CAS 88297-89-6) is primarily used as a thermal radical initiator in industrial polymerization, enabling controlled chain growth in vinyl monomers such as acrylates and methacrylates. In coatings and inks formulations, it may serve as a curing initiator for thermally cured systems, promoting crosslinking and film formation. It can be employed as an intermediate in organic synthesis to access salicylate derived peresters and related compounds. In adhesives and composites, it is evaluated as a curing initiator or processing additive to influence cure speed and polymer network development. It may also function as a building block in specialty polymers or resins, with usage governed by formulation limits and local regulations.
