General Description

Chlorophosphonazo I is a synthetic chemical compound used as a sensitive reagent for the spectrophotometric determination of phosphorus. It is a water-soluble dye that forms a stable complex with phosphorus, resulting in a color change from yellow to blue. This color change can be measured at a wavelength of 640 nm, allowing for the quantitative analysis of phosphorus in various samples. Chlorophosphonazo I is commonly employed in environmental and biological research to assess phosphorus levels in water, soil, and biological samples. It is known for its high sensitivity and accuracy in detecting trace amounts of phosphorus, making it a valuable tool in analytical chemistry.
