Quality Control

Our Cyclopentane-1,1-Dicarboxylic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Custom synthesis and purity grades (e.g., >98%, >99%) are available to meet specific project requirements.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect quality.
