Description

Ethyl 4-{[3-(4-Fluorophenyl)-6-Oxopyridazin-1(6H)-Yl]Acetyl}Piperazine-1-Carboxylate is a high-purity, advanced pharmaceutical intermediate designed for research and development. This compound is critical for medicinal chemists working on novel therapeutic agents, particularly in the areas of central nervous system (CNS) and inflammatory disease targets. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and fine chemical manufacturers requiring a reliable and consistent building block for complex synthesis.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for CNS-targeting drugs.
• Medicinal Chemistry Research: Used in lead optimization and structure-activity relationship (SAR) studies to develop new therapeutic candidates.
• Preclinical Development: Serves as a critical material for producing compounds required for pharmacological and toxicological evaluations.
• Contract Synthesis: Supplied to CROs and CDMOs for custom synthesis projects and scale-up activities.
• Reference Standard: Can be used as a high-purity analytical standard for method development and quality control in API manufacturing.
