Quality Control

Our Vitamin D2 Sulfate is produced under strict quality management protocols. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and MS. While we offer research-grade material, our processes are designed to meet the exacting standards required for advanced applications. A Certificate of Analysis (COA) detailing purity, assay, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere when not in use to prevent degradation.
