Quality Control

Our 29H,29H,31H-Phthalocyanine-C,C,C,C-Tetrasulfonic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay, sulfonation degree, and impurity profile are available upon request. We support customer audits and can provide material to meet specific research or production-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize moisture absorption. Keep away from incompatible materials.
