Description

Etoperidone CAS NO 52942-31-1 is a high-purity pharmaceutical intermediate and research chemical belonging to the piperazine derivative class. It serves as a critical building block in the synthesis of advanced active pharmaceutical ingredients (APIs) and is essential for research and development in medicinal chemistry. This compound is primarily sought by pharmaceutical manufacturers, contract research organizations (CROs), and academic institutions engaged in the development of new therapeutic agents.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel psychotropic and central nervous system (CNS) active pharmaceutical ingredients.
• Medicinal Chemistry Research: Used as a core scaffold or building block for structure-activity relationship (SAR) studies and lead optimization in drug discovery.
• Reference Standard: Serves as an analytical standard for quality control and method development in pharmaceutical laboratories.
• Biochemical Research: Employed in studies investigating receptor binding and pharmacological mechanisms.
• Custom Synthesis: Starting material for the contract manufacturing of specialized, non-commercial chemical entities for research purposes.
