Quality Control

Our production of 4-[(1,3-Dioxobutyl)Amino]Naphthalene-1-Sulphonic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with every shipment, supporting 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 area at a controlled 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. Keep away from incompatible materials.
