Description

2,3-Dihydro-1,3-Dioxo-1H-Perylo[3,4-Cd]Pyridine-8-Sulfonic Acid is a specialized, high-purity sulfonic acid derivative of a perylene-based heterocyclic system. This compound is valued for its unique structural and electronic properties, making it a critical intermediate for advanced material synthesis. It is primarily sought by research and development teams and production chemists in the pharmaceutical, agrochemical, and specialty dye industries for creating novel functional molecules.

Application

• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring a functionalized perylene core for biological activity or solubility enhancement.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, or plant growth regulators where the sulfonic acid group aids in formulation and bioavailability.
• Organic Electronic Materials: Acts as a precursor for n-type semiconductors, electron-transport materials, or photoactive layers in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs).
• Functional Dye & Pigment Manufacturing: Employed in the production of high-performance pigments, fluorescent dyes, and sensors due to the perylene backbone's photostability and chromophoric properties.
• Polymer Modification: Utilized to introduce sulfonic acid groups into polymers to create ion-exchange resins, proton-conducting membranes for fuel cells, or water-soluble polymer derivatives.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical reactions, catalysis, and material science applications.

Quality Control

Our 2,3-Dihydro-1,3-Dioxo-1H-Perylo[3,4-Cd]Pyridine-8-Sulfonic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which may affect product stability and performance.
