Quality Control

Our Benzenesulfonic Acid, 2-Nitro-, 4-Chlorobutyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and reducing agents. The container should be kept tightly sealed to minimize moisture absorption and decomposition.
