Quality Control

Our 3,4-Diaminobenzoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying, to ensure it meets exacting specifications for critical applications. Certificates of Analysis (COA) documenting all test results are provided with every shipment to guarantee traceability, consistency, and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize oxidation.
