Quality Control

Our Methyl 3-Isocyanatobenzoate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, color, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Keep away from heat, open flames, and sources of ignition. Isolate from strong bases, alcohols, amines, and water.
