Description

The Hydrogen(+1) Cation CAS NO 12408-02-5 is the fundamental positively charged ion (H⁺) formed upon the ionization of hydrogen. This species is central to a vast array of chemical and industrial processes, most notably as the defining component of acidity in Brønsted–Lowry acid-base theory. Its controlled generation, handling, and reaction are critical in sectors ranging from advanced materials synthesis to large-scale chemical manufacturing. Industrial buyers rely on consistent and high-purity sources of this reactive intermediate for process reliability and product quality.

Application

• Catalysis & Chemical Synthesis: Acts as a fundamental catalyst or co-catalyst in a wide range of organic transformations, including hydrogenation, polymerization, and isomerization reactions.
• pH Adjustment & Neutralization: Serves as the active species in acid treatments for pH control in wastewater treatment, metal finishing, and chemical process streams.
• Fuel Cell Technology: Essential as the charge carrier in proton-exchange membrane (PEM) fuel cells, where it is generated at the anode and transported to the cathode.
• Analytical Chemistry & Titration: Used as the standard reference in acid-base titrimetry for determining the concentration of basic substances.
• Materials Science & Etching: Employed in the etching and surface treatment of semiconductors, metals, and ceramics to modify surface properties.
• Energy Storage Research: Investigated in next-generation battery systems, such as proton batteries, where it functions as the charge carrier instead of lithium ions.
• Laboratory Reagent: Generated in-situ or supplied in various matrices for use as a key reagent in research and development laboratories.

Quality Control

Our production and handling protocols for reactive ionic species like the Hydrogen(+1) Cation are designed to ensure maximum purity and consistency. While it is typically generated and consumed in situ, we guarantee the quality of precursor materials and generation systems. Specifications for precursor acids or generation equipment are validated against stringent internal standards. A Certificate of Analysis (COA) detailing relevant parameters for the supplied system or precursor is available for every batch upon request.

Storage

As a highly reactive and transient species, the Hydrogen(+1) Cation is not stored in its isolated form. It is generated as needed from stable precursor compounds (e.g., strong mineral acids) or within specialized electrochemical cells. These precursor materials should be preserved in tightly closed, corrosion-resistant containers, stored in a cool, well-ventilated area separate from incompatible materials such as strong bases and reactive metals. Specific storage conditions are provided with the material safety data sheet (MSDS/SDS) for the precursor compound or generation system supplied.
