Description

Amoxicillin CAS NO 26787-78-0 is a broad-spectrum, β-lactam antibiotic belonging to the aminopenicillin class. It is a critical active pharmaceutical ingredient (API) valued for its bactericidal activity against a wide range of Gram-positive and some Gram-negative bacteria. This essential pharmaceutical intermediate is primarily required by manufacturers in the human and veterinary pharmaceutical industries for the formulation of oral and injectable antibiotic medications.

Application

Amoxicillin serves as the fundamental active component in a variety of antibiotic formulations. Its primary and derived applications include:

• Human Pharmaceutical Formulations: Core API for capsules, tablets, oral suspensions, and sachets used to treat bacterial infections such as pneumonia, bronchitis, and urinary tract infections.
• Veterinary Medicinal Products: Key ingredient in antibiotics for livestock, poultry, and companion animals to combat bacterial diseases.
• Combination Therapies: Used in fixed-dose combination drugs, most notably with clavulanic acid (as co-amoxiclav) to overcome β-lactamase mediated bacterial resistance.
• Research & Development: Serves as a reference standard and starting material in pharmaceutical R&D for developing new antibiotic derivatives and studying bacterial resistance mechanisms.

Quality Control

Our Amoxicillin is manufactured and tested under strict quality management systems. We ensure compliance with major pharmacopoeial standards, including USP, EP, and BP monographs. Each batch undergoes comprehensive analytical testing for identity, purity, potency, and specified impurities. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and degradation.
