Description

Meprednisone CAS NO 1247-42-3 is a synthetic glucocorticoid corticosteroid, a methylated derivative of prednisone. This compound is valued for its potent anti-inflammatory and immunosuppressive properties, making it a critical intermediate in advanced pharmaceutical synthesis. It is primarily required by research institutions and pharmaceutical manufacturers developing therapeutic agents for inflammatory and autoimmune conditions.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of more complex corticosteroid APIs (Active Pharmaceutical Ingredients).
• Biochemical Research: Used in laboratory studies to investigate glucocorticoid receptor activity, gene expression, and metabolic pathways.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in pharmaceutical testing laboratories.
• Anti-inflammatory Agent Development: A precursor in R&D programs aimed at creating new topical or systemic anti-inflammatory medications.

Quality Control

Our Meprednisone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade standards suitable for pharmaceutical research and development. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 low-humidity environment to prevent moisture absorption.
