  • Applications

    Valtrate (CAS 18296-44-1) is a valerian-derived lactone primarily encountered in research settings rather than as a commercial product. Typical applications include serving as an intermediate/building block in organic synthesis for pharmaceutical and agrochemical research, acting as a reference standard for analytical characterization of valerian-related natural products, and being studied as a scaffold in medicinal chemistry and natural products research focused on valerian constituents; use is subject to local regulations and formulation limits.
