Quality Control

Our production of Bis(5-Formyl-2-Hydroxybenzenesulfonic Acid)Calcium Salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry benchmarks. A Certificate of Analysis (COA) documenting purity, physical characteristics, and test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
