Quality Control

Our 5-Aminonaphthalen-1-Ol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

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