  • Applications

    Chloralose (CAS 15879-93-3) is primarily used in laboratory settings as an anesthetic/sedative for small animals and in neuroscience and physiology experiments, providing controlled anesthesia for moderate durations. It is also used as a specialty intermediate or reagent in organic synthesis and may appear in pharmaceutical research as a building block for derivative compounds. In analytical chemistry and academic laboratories, chloralose may be evaluated as a reagent for synthesis or sample preparation workflows. Its use is subject to local regulations and formulation limits.
