Overview
Ammonium Tetranitrooxoruthenate(VII), commonly known as ammonium perruthenate, is a ruthenium-based inorganic compound with the formula NH4RuO4. It is widely recognized for its strong oxidizing properties and is primarily used in organic synthesis as a catalyst. This compound is particularly valued in the pharmaceutical and fine chemical industries for its ability to facilitate selective oxidation reactions. Its dark brown crystalline form and solubility in various solvents make it a versatile reagent in laboratory and industrial settings.
Physical and Chemical Properties
Ammonium perruthenate is a dark brown to black crystalline powder that decomposes before melting. It is soluble in water and organic solvents, which enhances its utility in various chemical processes. The compound is a strong oxidizing agent, capable of oxidizing alcohols to aldehydes and ketones without over-oxidation. However, it is sensitive to moisture and heat, requiring careful handling and storage to maintain its efficacy and safety.
Main Applications
The primary application of ammonium perruthenate is as a catalyst in organic synthesis, particularly in oxidation reactions. It is extensively used in the pharmaceutical industry to produce intermediates for drug manufacturing. Additionally, it serves as a reagent in the synthesis of fine chemicals and specialty materials. Its ability to perform selective oxidations under mild conditions makes it a preferred choice for complex chemical transformations.
Safety and Storage
Ammonium perruthenate is highly toxic and poses significant health risks if inhaled, ingested, or absorbed through the skin. Proper personal protective equipment (PPE), including gloves, goggles, and lab coats, must be worn when handling this compound. Storage should be in a cool, dry place, away from reducing agents and incompatible materials. Containers must be tightly sealed to prevent moisture absorption and decomposition.
B2B Procurement Guide
When procuring ammonium perruthenate, B2B buyers should prioritize suppliers who provide detailed certificates of analysis (CoA) to verify purity and quality. Due to its hazardous nature, ensure that the supplier complies with all relevant safety and transportation regulations. Prices can vary significantly based on purity and quantity, typically ranging from $500 to $1000 per gram. Bulk purchases may offer cost savings, but storage and handling requirements must be carefully considered to avoid degradation or safety incidents.
