Quality Control

Our Potassium p-Aminophenyl Sulphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening. For long-term storage, consider using desiccants or storing under an inert atmosphere to prevent oxidation.
