Description

Cadmium Oxalate Trihydrate is an inorganic coordination compound where cadmium is complexed with oxalate ligands and associated with three water molecules. This material is valued for its role as a precursor in the synthesis of specialized cadmium-based materials and catalysts. It serves critical functions in research and development laboratories, as well as in industrial processes for electronics and chemical manufacturing where controlled cadmium sources are required.

Application

• Precursor for Cadmium Oxide/Chalcogenides: A key starting material in the synthesis of cadmium oxide (CdO) nanoparticles and cadmium chalcogenides (e.g., CdS, CdSe) for semiconductor and optoelectronic applications.
• Catalyst Synthesis: Used in the preparation of heterogeneous catalysts for organic transformations and oxidation reactions.
• Chemical Research & Development: Employed in academic and industrial R&D for studying coordination chemistry and developing new cadmium-containing compounds.
• Analytical Chemistry: Acts as a standard or reagent in specific gravimetric and analytical procedures.
• Pyrotechnic Compositions: Utilized in certain specialized pyrotechnic formulations to produce specific colored flames.
• Ceramic Glaze Component: Serves as a source of cadmium in the formulation of specific ceramic glazes and pigments.

Quality Control

Our Cadmium Oxalate Trihydrate is manufactured under controlled conditions to ensure batch-to-batch consistency. Quality is verified through a series of analytical tests including assay, loss on drying, and heavy metal screening. A Certificate of Analysis (COA) detailing purity and specific test results is provided with each shipment to ensure compliance with your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
