Quality Control

Our Sesquicillin is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediates. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your regulatory and quality needs.

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.
