Quality Control

Our Meso-Tetra(4-Sulfonatophenyl)Porphine Dihydrochloride is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectral analysis for identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, absorbance characteristics, and other critical parameters are available upon request to support your quality assurance protocols.

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); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which may affect stability and performance.
