Quality Control

Our production of 4-(3-Heptadecyl-4,5-Dihydro-4-Methyl-5-Oxo-1H-Pyrazol-1-Yl)Benzenesulphonic Acid adheres to stringent internal quality protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed to confirm identity, purity, and key physical parameters. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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.
