Quality Control

Our L-Tyrosine, 2-Ethyl-6-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis to confirm stereochemical integrity, and residual solvent screening. A detailed Certificate of Analysis (COA) is provided with every shipment, ensuring traceability and compliance with your research or development specifications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect stability and handling properties.
