Quality Control

Our Di-tert-Butylnaphthalenesulphonic Acid is manufactured under a stringent quality management system. Each batch is subjected to comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets precise customer specifications and consistent performance standards. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
