Quality Control

Our 6-Quinazolinecarboxaldehyde, 4-(2-Thienyl)- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
