Quality Control

Our Terephthalic Acid Bis-(Hydroxymethylamide) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, potency, and the absence of critical impurities. Certificates of Analysis (COA) documenting comprehensive testing results are 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 area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
