Quality Control

Our 3-(Tosyloxy)Propionic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under dry conditions to prevent degradation.
