Description

Fenbufen CAS NO 36330-85-5 is a non-steroidal anti-inflammatory drug (NSAID) belonging to the propionic acid derivative class. It serves as a key pharmaceutical intermediate and active pharmaceutical ingredient (API) for the synthesis of anti-inflammatory and analgesic medications. This compound is primarily required by pharmaceutical manufacturers and research institutions engaged in the development and production of prescription drugs targeting conditions like arthritis and musculoskeletal pain.

Application

• Pharmaceutical API: Primary use as the active ingredient in formulated anti-inflammatory and analgesic drugs.
• Arthritis Treatment: Used in medications for the management of osteoarthritis and rheumatoid arthritis symptoms.
• Analgesic Formulations: Incorporated into drugs designed to relieve mild to moderate pain.
• Musculoskeletal Disorder Drugs: A component in therapies for conditions like ankylosing spondylitis.
• Pharmaceutical R&D: Serves as a reference standard and building block in drug discovery and development programs.
• Generic Drug Manufacturing: Critical for the production of cost-effective generic versions of fenbufen-based medications.

Quality Control

Our Fenbufen is manufactured under strict quality management systems, targeting compliance with pharmacopeial standards such as USP and EP. Every batch undergoes comprehensive analytical testing including identification, purity assay, and impurity profiling to ensure it meets stringent specifications for pharmaceutical use. A Certificate of Analysis (COA) documenting all test results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed to minimize exposure to atmospheric moisture and light.
