Quality Control

Every batch of H 168/79 is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Our products are produced to meet the exacting standards required for pharmaceutical and fine chemical applications. A Certificate of Analysis (COA) detailing specific batch results 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
