Quality Control

Our Benzoic Acid, 4-Amino-, Hexyl Ester, Hydrochloride (1:1) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis, to ensure it meets exacting research and industrial-grade specifications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your project requirements.

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 sealed under dry conditions to prevent degradation. Keep away from incompatible materials.
