Description

Photobilirubin CAS NO 79619-29-7 is a light-sensitive bilirubin derivative, a critical compound in the study of neonatal jaundice and phototherapy mechanisms. Its primary value lies in its role as a reference standard and research material for investigating the photochemical breakdown pathways of bilirubin in the human body. This product is essential for pharmaceutical R&D laboratories, diagnostic kit manufacturers, and academic institutions focused on hepatology and metabolic disorders.

Application

• Pharmaceutical Reference Standard: Used for the calibration and validation of analytical methods (HPLC, LC-MS) in drug development and quality control.
• Phototherapy Research: A key reagent in studies investigating the efficacy and molecular mechanisms of light-based treatments for hyperbilirubinemia.
• Diagnostic Development: Serves as a critical component in the research and manufacturing of in-vitro diagnostic assays for liver function and bilirubin metabolism.
• Biochemical Research: Employed in enzymatic studies and metabolic pathway analysis related to heme catabolism and jaundice.
• Educational & Academic Use: Used in university laboratories for advanced teaching and research in medicinal chemistry and clinical biochemistry.

Quality Control

Our Photobilirubin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. We provide full traceability and Certificates of Analysis (COA) are supplied with every shipment to ensure compliance with your research and development protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) or as specified on the label or COA. This product is easily oxidized and light-sensitive; prolonged exposure to air or light should be avoided to maintain stability and purity.
