Description

Zhengguangmycin is a potent antibiotic compound belonging to the aminoglycoside class, widely recognized for its efficacy against a broad spectrum of Gram-negative bacteria. Its primary value lies in its application as a key active pharmaceutical ingredient (API) in the formulation of veterinary and, in some regions, human medicinal products. This makes it an essential raw material for manufacturers in the pharmaceutical, veterinary medicine, and aquaculture industries seeking reliable and high-purity antibiotic sources.

Application

• Veterinary Pharmaceutical API: Primary use as the active ingredient in injectable and topical formulations for treating bacterial infections in livestock and companion animals.
• Aquaculture Disease Control: Used in medicated feeds or baths to combat bacterial diseases in fish and shrimp farming operations.
• Human Pharmaceutical Intermediate: Serves as a critical starting material or intermediate in the synthesis of certain semi-synthetic antibiotic drugs under strict regulatory frameworks.
• Agricultural Bactericide: Formulated for the control of specific bacterial plant pathogens in high-value crops, though use is highly regulated.
• Microbiological Research: Employed as a selective agent in culture media and in studies of bacterial resistance mechanisms.
• Reference Standard: High-purity grades are used as analytical reference standards in quality control laboratories for drug testing and verification.

Quality Control

Our Zhengguangmycin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for potency, microbial limits testing, and residual solvent analysis, to ensure it meets stringent specifications for pharmaceutical use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 after each use to prevent moisture absorption, which can affect stability and potency. Keep away from incompatible materials.
