Quality Control

Our Tetrabutylammonium L-Lactate solution is manufactured under a strict quality management system. Each batch is tested to ensure consistent purity, concentration, and chiral integrity. A comprehensive Certificate of Analysis (COA) detailing assay, water content, specific rotation, and impurity profile is provided with every shipment to guarantee it meets your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C). The solution is hygroscopic; keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and potential changes in concentration.
