Description

Diammonium Hexachlororhenate is an inorganic coordination compound of rhenium, a rare and strategically important transition metal. This high-purity salt is a critical precursor material for advanced catalytic systems and specialized electronic applications. It is primarily utilized by research institutions and industrial manufacturers in the fields of catalysis, chemical vapor deposition (CVD), and materials science.

Application

• Catalyst Precursor: Serves as a key starting material for synthesizing high-performance rhenium-based catalysts used in petroleum refining, hydrogenation, and dehydrogenation reactions.
• Chemical Vapor Deposition (CVD): Used as a source compound for depositing thin films of rhenium or rhenium-containing alloys onto substrates for electronic and protective coatings.
• Materials Science Research: Employed in the development of novel inorganic compounds, coordination complexes, and advanced alloys due to its well-defined rhenium(IV) center.
• Laboratory Reagent: Acts as a standardized source of hexachlororhenate(IV) anions ([ReCl6]2-) for analytical and synthetic chemistry applications.
• Electroplating: Potential use in specialized electroplating baths for depositing rhenium coatings on components requiring high-temperature stability and wear resistance.

Quality Control

Our Diammonium Hexachlororhenate is manufactured under controlled conditions to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes rigorous analytical testing, including assay by titration and identification by infrared spectroscopy (IR). A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and physical characteristics is provided with every shipment to guarantee 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 nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product stability and performance.
