Quality Control

Our 2,4-Dichloro-6,7-Dimethoxyquinazoline is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements of pharmaceutical R&D and fine chemical synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent high quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 may affect stability and handling properties.
