Quality Control

Our 2,5-Dimethylsulphanilic Acid is produced under a stringent quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for sensitive synthetic applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
