Quality Control

Our Methyl 4-Amino-3-Chlorobenzoate is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and IR/NMR for structural confirmation, to ensure it meets exacting standards for use in sensitive applications like pharmaceutical synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 after opening to prevent degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
