Quality Control

Our 2,3-Butanediol is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing purity, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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. Keep away from strong oxidizing agents.
