  • Applications

    4-Piperidinol, 1-methyl- (CAS 106-52-5) is primarily used as an intermediate in the synthesis of piperidine-containing pharmaceuticals, providing a versatile building block for constructing amine- and heterocycle-containing compounds and enabling downstream functionalization (esters, ethers, or C–N bond formation). It also serves as a building block in the production of agrochemicals bearing the piperidine motif. In medicinal chemistry, it is used for library generation and SAR studies as a flexible precursor to various N-methyl piperidine derivatives. Additionally, it may be employed as a starting material for fragrance and odorant compounds or other specialty chemicals, by enabling further functionalization at the 4-piperidinol core, subject to local regulations and formulation limits.
