Quality Control

Our production of 2-Chloro-5-Formylbenzenesulphonic Acid adheres to stringent quality management protocols. Every batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets exacting specifications. Certificates of Analysis (COA) documenting all critical quality attributes are provided and can be tailored to support regulatory submissions for cGMP manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its strong acid nature, keep away from incompatible materials such as bases, reducing agents, and reactive metals. The container must be kept tightly sealed to minimize exposure to atmospheric moisture.
