Quality Control

Our 4-Methylumbelliferyl Caprylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for sensitive fluorogenic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and performance consistency for your critical research and diagnostic needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and desiccated after opening to maintain stability and prevent degradation.
