HPLC Method for Ethylphosphonic Acid, Methylphosphonic Acid, Methylenediphosphonic acid, Phosphate, Phosphoric Acid on Newcrom B by SIELC Technologies High Performance Liquid Chromatography (HPLC) Method for Analysis of Ethylphosphonic Acid, Methylphosphonic Acid, Methylenediphosphonic acid, Phosphate, Phosphoric Acid

Ethylphosphonic acid has a C₂H₅P(O)(OH)₂ chemical formula. It is typically found as white crystals or crystalline powder. It is often used as an internal standard when researching fosfomycin in human plasma as well as a synthetic nucleotide analog. Glyphosate is an herbicide with a chemical formula of C₃H₈NO₅P. It works through blocking enzymes, like 5-enolpyruvylshikimate-3-phosphate synthase, essential for plant growth. It is typically found in agricultural work, but can occasionally be found in forestry and garden care.

Methylphosphonic acid is an organophosphorus compound with the chemical formula CH₃P(OH)₂. It is often used in some lubricant additives, textile treatments, and in synthesis of phosphonate compounds, like the previously mentioned Glyphosate.

Methylenediphosphonic acid has the chemical formula CH₂[P(O)(OH)₂]₂. It is typically seen as a precursor in synthesis of Mesoporous aluminum organophosphate, if alkyltrimethylammonium, and Tetraester of methylenediphosphonic acids. Ethylphosphonic Acid, Methylphosphonic Acid, Methylenediphosphonic acid, Phosphate, Phosphoric Acid can be retained and analyzed using the Newcrom B stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a formic acid buffer. Detection is performed using CAD.
