Quality Control

Our 1,3-Azulenedicarboxylic Acid, 2-Amino- is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including HPLC, NMR, and mass spectrometry to verify identity, purity, and consistency. Certificates of Analysis (COA) detailing all test results are provided and available upon request 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.
