Quality Control

Every batch of n-(2 4-Dinitro-1-Naphthyl)-p-Toluenesulfonamide is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. Our standard analytical suite includes identification by spectroscopic methods, assay by HPLC, and control of key impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nitroaromatic structure, it should be stored separately from strong reducing agents and combustible materials.
