Quality Control

Our Pyridinium, 2-Hydroxy-1-Methyl-, Inner Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, identity confirmation by IR and NMR spectroscopy, and residual solvent analysis. Certificates of Analysis (COA) are available for every batch and supplied upon request to support your quality assurance and regulatory documentation needs.

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 each use to prevent degradation from atmospheric moisture.
