Quality Control

Our 2-Butanone, 1-Diazo-4-[[(4-Methylphenyl)Sulfonyl]Amino]- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging. Keep away from heat, sparks, open flames, and incompatible materials.
