Quality Control

Every batch of 4-Butyloxycarbonyl-1,2-Benzenedicarboxylic Anhydride is produced and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

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). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent exposure to atmospheric moisture, which can lead to hydrolysis and degradation of the anhydride functionality.
