Quality Control

Our production of 5-Isopropyl-3-Methylphenyl Chloroformate adheres to stringent quality management protocols. 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 customer specifications. Certificates of Analysis (COA) documenting all test results are provided as standard, guaranteeing traceability, consistency, and compliance with relevant industry standards.

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 hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
