Quality Control

Our 4-Isopropylcinnamic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal purity and stability.
