Quality Control

Our Butanetetracarboxylic Acid is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to meet exacting customer specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity and key physical-chemical parameters.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling.
