Quality Control

Our 1H-Pyrazole-5-Sulfonicacid,3-Acetyl-1-Methyl-(9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

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 an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and oxidizing agents.
