Description

Selenophene CAS NO 288-05-1 is a five-membered heterocyclic compound where a selenium atom replaces one of the carbon atoms in a thiophene ring. This unique structure makes it a valuable building block in advanced materials science, particularly for developing novel organic semiconductors and conductive polymers. It is primarily sought after by researchers and manufacturers in the electronics and specialty chemical industries for applications requiring specific electronic properties.

Application

• Organic Semiconductor Development: A key monomer for synthesizing selenophene-based polymers used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs).
• Conductive Polymer Synthesis: Serves as a precursor for creating polymers with enhanced electrical conductivity and environmental stability compared to thiophene analogs.
• Electroluminescent Materials: Used in the research and production of materials for organic light-emitting diodes (OLEDs) due to its favorable electron-transport characteristics.
• Chemical Synthesis Intermediate: Acts as a versatile intermediate in organic synthesis for pharmaceuticals and agrochemicals requiring the selenophene moiety.
• Material Science Research: Employed in academic and industrial R&D to study structure-property relationships in chalcogenophenes and to develop new functional materials.
• Sensor Technology: Investigated for use in chemical sensors where its electronic properties can be tuned for specific analyte detection.

Quality Control

Our Selenophene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive electronic applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity confirmation, and impurity profiles. For research and development purposes, we can supply material meeting specific purity grades upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to air and light should be avoided to maintain product integrity.
