Quality Control

Our L-Tryptophan, Butyl Ester, Monohydrochloride is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral purity verification, and identity confirmation (IR, NMR). We provide Certificates of Analysis (COA) with each shipment to ensure traceability and compliance with your research or cGMP guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
