Quality Control

Our Stx140 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods and purity assessment by chromatographic techniques. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your regulatory and quality assurance requirements.

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 minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants.
