Quality Control

Our D-Homocysteinesulfinic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for sensitive research applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment, chiral purity verification, and identity confirmation. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or inert atmosphere.
