Quality Control

Our L-Tyrosine Hydrochloride is manufactured under strict quality management systems. It is tested to meet high-purity standards suitable for pharmaceutical and nutraceutical applications, with potential compliance to relevant monographs such as USP and FCC. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every batch to ensure traceability and quality assurance.

Storage

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