Description

Clindamycin CAS NO 25507-13-5 is a potent lincosamide antibiotic derived from lincomycin. It is a critical active pharmaceutical ingredient (API) valued for its efficacy against anaerobic bacteria and certain protozoan parasites. This compound is essential for manufacturers in the pharmaceutical industry, particularly for the production of systemic and topical antibiotic formulations. Its reliable supply and consistent quality are paramount for ensuring the safety and efficacy of final medicinal products.

Application

• Primary use as an Active Pharmaceutical Ingredient (API) in the manufacture of systemic antibiotic capsules, tablets, and injectable solutions.
• Formulation of topical preparations such as gels, lotions, and creams for the treatment of acne vulgaris and other skin infections.
• Key component in vaginal creams and suppositories for treating bacterial vaginosis.
• Used in veterinary medicine for the treatment of infections in animals.
• Application in research and development for studying antibiotic mechanisms of action and resistance.
• Potential use as a reference standard in analytical laboratories for quality control and method validation.

Quality Control

Our Clindamycin is manufactured under strict quality management systems to ensure it meets the highest standards for pharmaceutical use. It is typically produced in compliance with major pharmacopoeial specifications such as USP, EP, and BP. Every batch undergoes comprehensive analytical testing, including identity, purity, and impurity profile analysis. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and potency. Keep away from incompatible materials.
