Quality Control

Our Undecanedioic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profile analysis, to ensure it meets precise specifications for high-purity applications. Certificates of Analysis (COA) documenting purity, physical properties, and conformance are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperature (15-25°C). Keep away from strong oxidizers, strong bases, and sources of ignition. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
