Description

Ammonium Aquapentachlororhodate(III) is a specialized inorganic coordination compound of rhodium, a precious metal of the platinum group. This material serves as a critical precursor in the synthesis of homogeneous catalysts and advanced materials due to its well-defined rhodium(III) center. It is primarily utilized by research institutions and industrial manufacturers in the chemical, pharmaceutical, and electronics sectors for applications requiring precise rhodium incorporation.

Application

• Homogeneous Catalyst Synthesis: A key starting material for preparing rhodium-based catalysts used in hydrogenation, hydroformylation, and carbonylation reactions.
• Electroplating & Surface Coating: Source of rhodium for specialized electroplating baths to deposit thin, corrosion-resistant rhodium films on electronic components and jewelry.
• Materials Science Research: Precursor for the development of novel coordination polymers, metal-organic frameworks (MOFs), and other advanced inorganic materials.
• Pharmaceutical Intermediates: Used in the research and small-scale production of active pharmaceutical ingredients (APIs) involving rhodium-catalyzed steps.
• Analytical Chemistry: Serves as a standard or reference material in spectroscopic analysis and other analytical techniques for rhodium quantification.

Quality Control

Our Ammonium Aquapentachlororhodate(III) is manufactured under controlled conditions to ensure batch-to-batch consistency. Quality is verified through a suite of analytical techniques including titration for assay, ICP-OES/AAS for rhodium content and metallic impurities, and IR spectroscopy for identification. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption and decomposition. Keep away from incompatible materials.
