Quality Control

Our 4-(5-Amino-1-Oxa-2-Aza-3-Azoniacyclopenta-2,4-Dien-3-Yl)Butanoic Acid Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting research and process chemistry standards. Comprehensive Certificates of Analysis (COA) with batch-specific data are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and incompatible materials.
