Quality Control

Our Tetraglycine is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, chiral purity, and residual solvent analysis, to meet the stringent requirements of our global clientele. Certificates of Analysis (COA) are available for every batch and provided upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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 stability and performance.
