Quality Control

Our 4-Pentylphenyl Isocyanate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by HPLC and impurity profiling, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and specific test results are available upon request 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 a controlled room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture.
