Dojindo Molecular Technologies Inc Nitroso-PSAP (100MG), CAS: 80459-15-0, is a highly sensitive water-soluble colorimetric reagent for Fe(II) detection.

Supplier: Dojindo Molecular Technologies Inc N01010
Nitroso-PSAP is a highly sensitive water-soluble colorimetric reagent for Fe(II) detection that forms a green complex with Fe(II) (max=756 nm, =4.5x104 ). This reagent is suitable for the determination of blood serum levels of Fe, Co, Ni, and Cu. The detection range is from 5 ppb to 5 ppm under the same detection condition. Nitroso-PSAP is useful in flow injection analysis with a workable pH range of the nitroso compounds is 5.6-10.1. The molar absorptivities and maximum wavelengths of the Co, Cu, and Ni complexes are 4.0x104 (490 nm), 2.8x104 (429 nm), and 2.6x104 (394 nm), respectively. Dojindo has various chromogens used for chemical clinical assays. (https://www.dojindo.com/chromogens/)
