Quality Control

Our (S)-(+)-S-Methyl-S-Phenylsulfoximine is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high enantiomeric purity, which is critical for sensitive asymmetric synthesis. We provide comprehensive Certificates of Analysis (COA) with each batch, detailing key parameters such as chiral purity (HPLC), chemical purity, and identity confirmation. Our quality system is designed to support cGMP (current Good Manufacturing Practice) requirements for advanced pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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. For long-term storage, consider using desiccants or storing under an inert atmosphere.
