Quality Control

Our L-Homocysteinesulfinic Acid is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including identity confirmation by IR and NMR, purity assessment by HPLC, and specific tests for related substances and moisture. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, ensuring compliance with research-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
