Description

Guanidinomethylphosphonic Acid CAS NO 55215-14-0 is a specialized organophosphorus compound featuring a unique guanidine-phosphonic acid structure. This molecular architecture makes it a highly effective chelating agent and a versatile intermediate for synthesizing more complex functional molecules. It is primarily sought after by manufacturers in the water treatment, agrochemical, and pharmaceutical industries for its ability to bind metal ions and modify surface properties. Its utility extends to applications requiring scale inhibition, corrosion control, and as a building block for advanced materials.

Application

• Water Treatment Formulations: Acts as a high-performance scale and corrosion inhibitor in industrial cooling and boiler water systems.
• Agrochemical Synthesis: Serves as a key intermediate in the production of herbicides and plant growth regulators with enhanced bioavailability.
• Pharmaceutical Intermediates: Used in the synthesis of novel drug candidates, particularly those targeting bone diseases or requiring metal-chelating properties.
• Detergent & Cleaning Agents: Functions as a builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺) in industrial and institutional cleaning products.
• Personal Care Products: Incorporated into formulations such as oral care (anti-tartar agents) and skincare for its stabilizing and chelating effects.
• Textile & Paper Processing: Utilized as a processing aid for bleaching stabilization, dyeing, and as a dispersant to improve product quality.
• Metal Surface Treatment: Employed in plating baths and metal cleaning solutions to control precipitation and improve finish quality.
• Research & Development: Serves as a valuable ligand in coordination chemistry and material science research for creating metal-organic frameworks (MOFs) or catalysts.
