Description

Ammonium Cerium(IV) Sulfate is an inorganic salt of cerium in its +4 oxidation state, widely recognized as a powerful and selective oxidizing agent in synthetic chemistry. Its primary commercial value lies in its stability and solubility in aqueous sulfuric acid, making it a preferred reagent over other cerium(IV) sources for controlled oxidation reactions. This compound is essential for manufacturers and R&D laboratories in the pharmaceutical, fine chemical, and analytical sectors, where precise and efficient oxidation is required.

Application

• Organic Synthesis: A key reagent for the oxidation of alcohols to aldehydes or ketones (e.g., in the production of pharmaceutical intermediates).
• Analytical Chemistry: Used as a titrant in cerimetry (cerimetric titrations) for the quantitative analysis of reducing agents like ferrous ions or organic compounds.
• Pharmaceutical Manufacturing: Employed in the synthesis and purification steps of various active pharmaceutical ingredients (APIs) requiring selective oxidation.
• Catalyst and Catalyst Precursor: Serves as a catalyst or a precursor in oxidation processes and in materials science research.
• Electroplating & Surface Treatment: Used in specialized electroplating baths and for surface conditioning of metals.
• Research & Development: A standard laboratory chemical for developing new synthetic methodologies and studying oxidation mechanisms.

Quality Control

Our Ammonium Cerium(IV) Sulfate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards, including assay by cerimetric titration and control of key impurities. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee batch-to-batch consistency and traceability for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and a strong oxidizer; keep the container tightly sealed when not in use and store separately from reducing agents and combustible materials.
