Description

Singlet Oxygen CAS NO 17778-80-2 is an electronically excited, metastable state of molecular oxygen with distinct chemical reactivity compared to its ground state (triplet oxygen). This high-energy species is a powerful and selective oxidizing agent, making it invaluable for advanced chemical synthesis and research. It is essential for industries and laboratories focused on photodynamic therapy, organic synthesis, materials science, and environmental remediation.

Application

• Photodynamic Therapy (PDT) Research: A key cytotoxic agent used in the development and testing of photosensitizers for cancer treatment and antimicrobial applications.
• Advanced Organic Synthesis: Employed in selective oxidation reactions, including the synthesis of fine chemicals, pharmaceuticals, and the generation of endoperoxides.
• Materials Science & Polymer Chemistry: Used to study and induce polymer degradation, cross-linking, and the modification of surface properties.
• Environmental Chemistry: Applied in research for the oxidative degradation of pollutants and in advanced oxidation processes for water treatment.
• Chemical Sensing & Analysis: Serves as a reactive intermediate in the development of chemiluminescent probes and sensors for biological and chemical detection.
• Photochemistry & Reaction Mechanism Studies: A fundamental reagent for investigating reaction pathways, quenching studies, and the kinetics of photo-oxidation.

Quality Control

Our Singlet Oxygen is produced and handled under stringent conditions to ensure high reactivity and purity for research applications. While specific purity grades (e.g., for photochemical or synthetic use) are available, all materials are characterized to confirm their identity and state. A Certificate of Analysis (COA) detailing generation method and assay is provided to support your critical research and development work.

Storage

Singlet oxygen is a transient, highly reactive species and is typically generated in situ for immediate use in reaction systems. It cannot be stored in conventional containers. The precursor compounds or generation equipment should be stored according to their specific safety data sheets. Generated singlet oxygen must be used promptly in a controlled, inert atmosphere to prevent rapid quenching and reaction with solvent or apparatus materials.
