Quality Control

Our Virginiamycin Butanolide A is produced and tested under strict quality management systems. Each batch undergoes comprehensive analysis including identification, purity assay, and impurity profiling to ensure it meets high-grade standards suitable for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

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) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and handled under appropriate conditions to maintain stability.
