Quality Control

Our 5-Sulfo-1,2,4-Benzenetricarboxylic Acid is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. We provide full traceability and Certificates of Analysis (COA) are available upon request, detailing purity, identity, and impurity profiles to support your quality assurance protocols.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
