Description

Manganese(III) Citrate is a coordination complex where manganese is in the +3 oxidation state, chelated by citrate ligands. This compound is valued for its role as a source of bioavailable manganese and its unique redox properties, making it a critical material in advanced industrial and nutritional applications. It is essential for manufacturers in the animal nutrition, chemical synthesis, and specialty catalyst sectors seeking a high-purity, consistent manganese source. The product is supplied under the CAS registry number 5968-88-7.

Application

• Animal Feed Premixes: As a trace mineral source to prevent manganese deficiency and support bone development and metabolic functions in livestock and poultry.
• Chemical Synthesis & Catalysis: Acts as a precursor or catalyst in organic oxidation reactions and the synthesis of other manganese-based compounds.
• Nutraceutical & Dietary Supplements: Used in the formulation of specialized human and veterinary supplements requiring a highly bioavailable form of manganese.
• Laboratory Research & Reagents: Serves as a standard or starting material in biochemical and inorganic chemistry research.
• Specialty Ceramics & Pigments: A potential additive for colorants and in the production of certain electronic ceramics.
• Water Treatment & Soil Amendment: Utilized in micronutrient fertilizers and in specific wastewater treatment processes.

Quality Control

Our Manganese(III) Citrate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and heavy metal content. A comprehensive Certificate of Analysis (COA) documenting results for assay, moisture, and impurity limits is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize oxidation.
