Quality Control

Our production of Benzenesulfonic Acid, 4-Amino-, Monosodium Salt, Polymer With Formaldehyde And Methylphenol adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of sulfonation degree, molecular weight distribution, and ionic capacity. Certificates of Analysis (COA) documenting purity, solid content, pH, and other critical parameters 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 after initial use to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
