Quality Control

Our Isopentyl 4-Aminobenzoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for use in sensitive applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere such as nitrogen to preserve stability and prevent degradation.
