Description

Trisodium (2S-Trans)-18-Carboxylato-20-(Carboxylatomethyl)-13-Ethyl-12-Formyl-2,3-Dihydro-3,7,17-Trimethyl-8-Vinyl-21H,23H-Porphine-2-Propionate is a high-purity, water-soluble porphyrin derivative, a key intermediate in the synthesis of advanced photosensitizers and functional dyes. Its precise molecular structure makes it invaluable for research and development in photodynamic therapy (PDT) and as a building block for novel materials. This compound is essential for pharmaceutical R&D laboratories, specialty chemical manufacturers, and academic institutions focused on photochemistry, catalysis, and biomedical imaging.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of photosensitizing agents for Photodynamic Therapy (PDT) targeting cancer and antimicrobial applications.
• Biomedical Research: Used as a fluorescent probe or a model compound in studies of porphyrin metabolism, heme biosynthesis, and cellular imaging.
• Catalysis Development: Serves as a ligand or a core structure for designing novel metalloporphyrin catalysts for oxidation and other organic transformations.
• Advanced Materials: A building block for creating functional dyes, light-harvesting arrays, and molecular sensors due to its strong chromophoric properties.
• Analytical Chemistry: Can be utilized as a standard or a reagent in spectrophotometric and chromatographic method development.

Quality Control

Our Trisodium 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 is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We can support development projects with material meeting in-house specifications aligned with pharmaceutical intermediate standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and handled under subdued light to maintain stability.
