Quality Control

Our Diisobutylnaphthalene-2-Sulphonic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profile, and physical property verification, to ensure it meets precise customer requirements and industry standards. A Certificate of Analysis (COA) documenting all test results is provided with every shipment 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; containers must be kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
