Quality Control

Our β-Tethymustine is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity, suitable for demanding research applications. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling via advanced techniques like HPLC and NMR. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to support your regulatory and quality documentation needs.

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 strictly light-sensitive nature, the container must be opaque or stored in dark conditions to prevent degradation. Keep the container tightly sealed when not in use.
