Quality Control

Every batch of 1,2-Benzenedicarboxylic Acid 1-(5-Carboxy-2-Ethyl-4-Hydroxypentyl) Ester is produced and tested under a strict quality management system to ensure it meets the high standards required for sensitive synthesis applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing detailed data for parameters including identity, purity, and specific impurities.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
