Quality Control

Our Quinazoline-2-Carbaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee batch-to-batch consistency and traceability.

Storage

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