Description

2(3H)-Furanone, 4-Amino-5-Ethynyldihydro- (9Ci) is a specialized heterocyclic building block featuring a fused furanone core with both amino and ethynyl functional groups. This unique molecular architecture makes it a highly valuable intermediate for synthesizing complex molecules in pharmaceutical and advanced material research. It is primarily sought after by R&D chemists and process development scientists working in medicinal chemistry and fine chemical synthesis.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for targeted therapies.
• Medicinal Chemistry Research: Used in hit-to-lead optimization and library synthesis for drug discovery programs, leveraging its reactive handles for diversification.
• Chemical Biology Probes: Employed in the development of molecular probes and tags due to the bio-orthogonal reactivity of the alkyne group.
• Advanced Material Synthesis: Acts as a monomer or cross-linking agent in the development of specialty polymers with tailored properties.
• Agrochemical Research: Utilized in the discovery and synthesis of new crop protection agents and plant growth regulators.
