Quality Control

Every batch of this product is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Specifications are aligned with research-grade and analytical standard requirements. A detailed Certificate of Analysis (COA) providing batch-specific results for purity, heavy metals, and related substances is provided with each shipment and is available 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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance.
