Description

(12S,13S)-3,8,13,17-Tetrakis(Carboxymethyl)-12,13-Dihydro-13-Methyl-21H,23H-Porphyrin-2,7,12,18-Tetrapropanoic Acid is a high-purity, synthetically derived porphyrin derivative with a complex, functionalized structure. This compound is of significant value as a key intermediate and a versatile ligand for the development of advanced materials and catalysts, particularly in photodynamic therapy research and coordination chemistry. It is primarily needed by R&D laboratories, pharmaceutical innovators, and specialty chemical manufacturers working on next-generation medical diagnostics, light-harvesting systems, and metal-organic frameworks.

Application

• Pharmaceutical Research & Development: Serves as a critical precursor or active pharmaceutical ingredient (API) intermediate in the synthesis of novel compounds for photodynamic therapy (PDT) and other light-activated treatments.
• Coordination Chemistry & Catalyst Design: Acts as a sophisticated multidentate ligand for chelating various metal ions (e.g., lanthanides, transition metals) to create highly specific catalysts or molecular sensors.
• Advanced Material Science: Used in the development of organic semiconductors, dye-sensitized solar cells (DSSCs), and other optoelectronic devices due to its porphyrin-based photophysical properties.
• Analytical Chemistry & Diagnostics: Employed as a specialized reagent or a core structure in the design of fluorescent probes, biosensors, and contrast agents for medical imaging.
• Chemical Synthesis: Functions as a complex building block for the total synthesis of natural products or for introducing porphyrin motifs into polymers and dendrimers.

Quality Control

Our (12S,13S)-3,8,13,17-Tetrakis(Carboxymethyl)-12,13-Dihydro-13-Methyl-21H,23H-Porphyrin-2,7,12,18-Tetrapropanoic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, MS), to ensure it meets the stringent requirements for research and development applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

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 compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation and absorption of moisture.
