Description

4-[4-[(2-Bromophenyl)Methyl]-1-Piperazinyl]Benzoic Acid Ethyl Ester-D8 is a deuterated analog of a key pharmaceutical intermediate, offering enhanced stability and utility in advanced research and development. This compound is critical for conducting precise metabolic and pharmacokinetic studies, providing invaluable data for drug discovery and development pipelines. It is primarily sought by pharmaceutical R&D laboratories, contract research organizations (CROs), and manufacturers of active pharmaceutical ingredients (APIs) for use in deuterium labeling and tracer applications.

Application

• As a deuterated internal standard for the accurate quantification of its non-deuterated counterpart in bioanalytical methods using LC-MS/MS.
• In pharmacokinetic (PK) and drug metabolism studies to track the absorption, distribution, metabolism, and excretion (ADME) of lead compounds.
• For mechanistic studies in medicinal chemistry, leveraging deuterium kinetic isotope effects (DKIE) to probe reaction pathways and improve drug stability.
• As a key synthetic intermediate in the development of novel deuterated drug candidates for enhanced therapeutic profiles.
• In academic and industrial research focused on neuropharmacology, given the structural relevance of the piperazine moiety to central nervous system (CNS) targets.
