Quality Control

Our 3-Methyl-4-(2-Methyl-4-Oxo-3(4H)-Quinazolinyl)Benzoic Acid 2-(Diethyla Mino)Ethyl Ester Hcl is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, typically verified by HPLC, NMR, and IR spectroscopy. We adhere to cGMP principles where applicable to support our clients' pharmaceutical development 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Long-term storage under inert atmosphere is recommended.
