Quality Control

Every batch of 2,6-Diamino-4-Hydroxyquinazoline is manufactured and tested under a strict quality management system. We ensure compliance with rigorous internal specifications, which are designed to meet the high standards required for pharmaceutical and research applications. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee traceability and product integrity.

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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
