Quality Control

Our n-o-Tolyl-Guanidine Hydrochloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent internal specifications, which typically include tests for identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing these results is provided with every shipment to guarantee compliance with your technical requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
