Description

Nitrohydrochloric Acid, also known as aqua regia, is a highly reactive and corrosive mixture of concentrated nitric and hydrochloric acids. This powerful reagent is essential for dissolving noble metals like gold and platinum, which are resistant to most other acids. It is a critical material for precious metal refining, analytical chemistry, and specialized industrial cleaning and etching processes.

Application

• Precious Metal Refining and Recovery: Primary industrial use for dissolving and processing gold, platinum, and palladium.
• Analytical Chemistry & Sample Digestion: Used in laboratories for digesting difficult-to-dissolve samples for trace metal analysis.
• Microelectronics & Semiconductor Fabrication: Employed in cleaning and etching processes for high-purity substrates and components.
• Industrial Equipment Cleaning: Effective for cleaning and descaling specialized laboratory glassware and metal apparatus.
• Chemical Synthesis & Catalyst Production: Serves as a potent reagent in specific inorganic synthesis and catalyst preparation.
• Research & Development: Utilized in material science and metallurgical research for its unique solvent properties.

Quality Control

Our Nitrohydrochloric Acid is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability. Each lot is tested to confirm its reactivity profile and concentration specifications. Certificates of Analysis (COA) detailing key parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed, acid-resistant container, protected from light. Store in a cool, well-ventilated, dedicated acid storage area, away from incompatible materials such as organic compounds, bases, and reducing agents. Due to its highly volatile and corrosive nature, containers must be kept upright and securely sealed to prevent fume release.
