Quality Control

Our Tylosin B is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous in-house specifications, which are aligned with common pharmacopeial standards for antibiotic substances. A comprehensive Certificate of Analysis (COA) detailing purity, potency, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
