Quality Control

Our Tetradecanedioic Acid is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profile analysis. Certificates of Analysis (COA) documenting all test results are available for review and download to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
