Quality Control

Our Sodium 3,4-Dichlorobenzenesulfonate is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and consistency. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
