Quality Control

Our D-Valine, 3,5-Dimethylphenyl Ester is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, chiral purity (enantiomeric excess), and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all specifications are available upon request for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere if necessary to prevent degradation.
