Used in the chemical synthesis process as an intermediate for producing pharmaceuticals targeting histamine H3 receptor antagonists, particularly in central nervous system research such as treatments for memory impairment, Alzheimer's disease, and sleep-related disorders. This compound serves as a key intermediate in constructing structures specific to the H3 receptor, which helps regulate neurotransmitter release in the brain. Additionally, it is used as a reference in laboratory settings to develop asymmetric synthesis methods, leveraging its chiral oxazoline group with an asymmetric center to control molecular environmental purity.
