Quality Control

Our 1-Methylquinolinium Toluene-p-Sulphonate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your research or production specifications.

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.
