Quality Control

Our production of 2-Pentanone, 4-Isocyanato-4-Methyl- adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture ingress. Keep away from heat, sparks, and open flame.
