Description

Ethyl (E)-4-(5-(3-((3-Carbamoyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)amino)-2-cyano-3-oxoprop-1-en-1-yl)furan-2-yl)benzoate is a high-purity, complex heterocyclic organic compound featuring a fused tetrahydrobenzothiophene core, a furan linker, and a benzoate ester terminus. This molecular architecture makes it a critical advanced intermediate for the synthesis of novel active pharmaceutical ingredients (APIs) and functional materials. It is primarily sought by pharmaceutical R&D and fine chemical synthesis teams working on innovative drug discovery programs.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the research and development of new therapeutic agents, particularly in oncology and central nervous system (CNS) drug discovery.
• Organic Synthesis Reagent: Used in advanced multi-step organic synthesis to construct complex molecular frameworks due to its reactive functional groups (amino, cyano, ester).
• Chemical Biology Probe Development: Employed in the design and synthesis of molecular probes for studying biological pathways and target validation.
• Material Science Research: Potential precursor for the development of organic semiconductors or photoactive materials, given its conjugated system and heterocyclic components.
• Contract Research & Manufacturing (CRMO): Supplied to organizations specializing in custom synthesis and process development for client-specific molecules.

Quality Control

Our Ethyl (E)-4-(5-(3-((3-Carbamoyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)amino)-2-cyano-3-oxoprop-1-en-1-yl)furan-2-yl)benzoate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing including HPLC, NMR, and MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
