Quality Control

Our production of 3-[Acetyl(Butyl)Amino]-4-Methoxybenzenesulfonic Acid Chloride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all critical parameters is provided with each shipment, guaranteeing traceability and consistent performance in your synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from moisture, strong bases, and oxidizing agents.
