Quality Control

Our Almecillin is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure identity, purity, and consistency, meeting specifications suitable for use as a pharmaceutical intermediate. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to ensure full traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled 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.
