Quality Control

Our 2-(4-Butyl-1-Piperazinyl)-4-Pentyloxyquinazoline Fumarate 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 for pharmaceutical intermediates. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to support regulatory filings.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
