Ammonia solution
Ammonia solution (CAS: 7664-41-7, Formula: NH₃, MW: 17.03) is a colourless liquid with a pungent odour, supplied as a 2.0 M solution in ethanol. This inorganic base is a crucial reagent in chemical synthesis and as a versatile laboratory chemical. Its primary applications include use as a pH adjuster, in various organic and inorganic reactions, and as a precursor for nitrogen-containing compounds. Tech Serve Solutions provides this essential chemical for research and industrial needs.
pH Adjustment
As a basic solution, ammonia is widely used to increase the pH of aqueous and non-aqueous systems. It is effective in neutralising acidic solutions and controlling reaction conditions where a basic environment is required.
Chemical Synthesis
Ammonia serves as a fundamental building block and reagent in organic and inorganic synthesis. It is employed in reactions such as amination, the synthesis of amines, and the formation of various nitrogen-containing heterocycles.
Laboratory Reagent
This ammonia solution is a standard reagent in analytical and synthetic laboratories. Its properties make it useful for a range of benchtop procedures, including titrations and sample preparation.
Cleaning and Degreasing
Dilute ammonia solutions are historically used for their ability to break down grease and organic residues. While less common for this specific ethanol solution, the inherent properties of ammonia lend themselves to cleaning applications in certain industrial contexts.
