Quality Control

Our 4-Hydroxy-1H-Indole-2-Carboxylic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
