Description

(5As, 10Br)-(-)-5A,10B-Dihydro-2-(Pentafluorophenyl)-4H,6H-Indeno[2,1-B][1,2,4]Trizolo[4,3-D][1,4]Oxazinium Tetrafluoroborate is a high-purity, structurally complex heterocyclic salt designed for advanced synthetic and research applications. Its unique fused ring system and chiral center make it a critical building block for developing novel pharmaceuticals and functional materials. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and specialty chemical industries who require precise, high-quality intermediates for complex synthesis.

Application

• Pharmaceutical Intermediate: Serves as a key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and anti-infective drug candidates.
• Agrochemical Research: Used in the development of novel herbicides and pesticides, leveraging its unique heterocyclic structure for biological activity.
• Material Science: Acts as a monomer or dopant in the creation of advanced organic electronic materials, such as OLEDs and conductive polymers.
• Asymmetric Catalysis: Employed as a ligand or catalyst component in enantioselective synthesis due to its chiral indeno-triazolo-oxazinium framework.
• Academic & R&D: A valuable tool for methodological studies in organic chemistry, including novel cyclization and fluorination reactions.
• Fluorinated Compound Synthesis: The pentafluorophenyl group provides a handle for further functionalization, making it useful in synthesizing other fluorinated specialty chemicals.
