Description

Pheophorbide A is a chlorophyll-derived porphyrin compound widely recognized for its photodynamic properties. This high-purity intermediate is critical for research and development in advanced therapeutic and diagnostic applications. It serves as a key building block for scientists and manufacturers in the pharmaceutical, biotechnology, and photodynamic therapy sectors.

Application

• Photosensitizer in Photodynamic Therapy (PDT): A core component in the development of novel anti-cancer and antimicrobial treatments, where it generates reactive oxygen species upon light activation.
• Biochemical Research: Used as a standard or probe in studies related to chlorophyll metabolism, photosynthesis, and porphyrin chemistry.
• Diagnostic Agent Development: Employed in the synthesis of targeted imaging agents for fluorescence-guided surgery and optical diagnostics.
• Natural Product Synthesis: Serves as a sophisticated precursor for the semi-synthesis of other chlorophyll derivatives and complex natural products.
• Material Science: Investigated for use in organic solar cells and light-harvesting materials due to its strong absorption in the visible spectrum.

Quality Control

Our Pheophorbide A is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. For long-term storage, desiccate to protect against moisture. Allow the product to equilibrate to room temperature in the sealed container before opening to prevent condensation.
