Quality Control

Our 2,4-Dimethylaniline-6-Sulfonic Acid is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for sensitive synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

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 to prevent absorption of atmospheric moisture, which can affect product quality.
