Quality Control

Our L-Homocysteine Sulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with detailed results from methods including HPLC, NMR, and elemental analysis. While produced to meet the exacting standards of research and development, specifications can be aligned with specific pharmacopeial or customer requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed immediately after use to minimize exposure to atmospheric moisture and light.
