Quality Control

Our Isophthalamic Acid, 4-Hydroxy-N,n-Dimethyl- is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting compliance in cGMP and ISO 9001 environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect purity and handling properties.
