Quality Control

Our production of Benzenesulfonic Acid, 4-Ethoxy-2-Methyl- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and titration methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
