Quality Control

Our L-Lysine o-Acetoxybenzoate is manufactured under a quality management system compliant with cGMP principles. Each batch is subjected to rigorous analytical testing, including identification, assay, and impurity profiling, to ensure it meets stringent pharmaceutical-grade specifications. A comprehensive Certificate of Analysis (COA) detailing purity, chiral purity, and residual solvent levels is provided with every shipment to guarantee traceability and compliance.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent degradation due to moisture absorption.
