Ceric Ammonium Sulphate (CAS 10378-47-9), also called as Ceric IV ammonium sulfate, is a bright yellow-orange double salt renowned as a powerful and stable oxidizing agent. It's structure, which includes the ammonium ion, provides superior stability and solubility in dilute sulphuric acid compared to standard Ceric sulfate salts, which makes it an ideal primary standard for cerimetry and a preferred redox titration reagent in quantitative analysis, as demonstrated by the frequent search for the accurate 0.1N solution form. In industrial and scientific use, the compound is primarily sold as an analytical standard to determine the concentration of reducing agents. Ammonium cerium sulfate utilised as a selective Cerium IV oxidation agent in synthesis for specialised organic chemistry applications. We are a leading & trusted CERIC AMMONIUM SULFATE supplier worldwide, offering high-purity Cerium Oxide and many RRes that meets quality and safety standards, with reliable lead times and global supply capability.

Primary standard for redox titrations in quantitative analysis. Accurately determine the concentration of reducing agents like iron (Fe2⁺), thiosulphate, and organic
Strong, selective oxidising agent, notably in the oxidation of organic compounds and in polymerisation initiation reactions
Employed in specialised methods for determining the chemical oxygen demand (COD) or the presence of specific contaminants.
Highly pure source of Cerium for specialized applications where contamination from other anions is undesirable
Ambient temperature
Temp @ +15°C to +25°C.
Store in a well-ventilated place
Keep container tightly closed & Locked
Presence of the ammonium ion in the double salt makes it more stable and soluble, particularly in the dilute $\text{sulphuric}$ acid medium used for titrations. This increased stability allows it to be used as a primary standard (weighed directly for high accuracy), simplifying titration preparation and standardization.
critical indicator is Assay Purity and Insolubles. Since it's used as an analytical standard, the minimum required purity must be 99.9% or higher. Any insolubles can interfere with clear endpoint detection in titrations
Export ready with provided certificate of analysis Ceric Ammonium Sulphate COA confirming its exact oxidizing power.
Ceric Ammonium Sulphate is a downstream, high-purity derivative. It is manufactured by starting with refined Cerium salts often Cerium Nitrate or Sulphate, which are ultimately sourced from the same Rare Earth Elements & Compounds value chain as CeO₂.
Yes, it can. While Potassium Dichromate is the most common COD standard, Ceric Ammonium Sulphate is used in specialized or research methods because the reduction product (Ce3+) is colorless, which can simplify spectrophotometric analysis.
Solution form supplied for convenience and accuracy. Preparing a highly accurate volumetric standard from the solid (dihydrate) is time-consuming and prone to error. Supplying a pre-standardised 0.1N solution saves laboratories significant time and guarantees the required precision for routine QC testing.
