Quality Control

Every batch of 2-Furancarboxylicacid,5-(Isocyanomethyl)-,Ethylester(9Ci) is produced and tested under strict quality management protocols to ensure consistency and purity for critical R&D and production applications. Our standard grade typically meets a purity specification of ≥95% (by HPLC), with detailed impurity profiling available. Certificates of Analysis (COA) are provided with each shipment, and custom synthesis to meet specific purity or analytical requirements can be arranged.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this compound should be stored under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Keep the container tightly sealed in a cool, dry, and well-ventilated place, away from heat, sparks, and open flames. Use appropriate grounding procedures when handling.
