4-(2-Pyridylazo)resorcinol (PAR) is a monosodium salt(1), dibasic acid that forms the protonated complexes with most metal ions.
Anwendung
4-(2-Pyridylazo)resorcinol (PAR) serves as a metallochromic indicator and is suitable as a chromogenic agent for the quantitative determination of over 50 elements.

Literature reports of the efficacy of para-sulfonatocalix[6]- and calix[8]-arenes as U(vi) complexants indicated that they might be useful for in vivo chelation of the novel therapeutic alpha-emitter (230)U. We have studied the complexation of U(vi) with para-sulfonatocalix[6]arene and para-sulfonatocalix[8]arene by
In this study, X-ray photoelectron spectroscopy (XPS) was used to study chitosan-graphene oxide (chitosan-GO) incorporated with 4-(2-pyridylazo)resorcinol (PAR) and cadmium sulfide quantum dot (CdS QD) composite thin films for the potential optical sensing of cobalt ions (Co2+). From the XPS

The biosynthesis of the dinuclear metal cluster at the active sites of the [NiFe]-hydrogenase enzymes is a multi-step process executed by a suite of accessory proteins. Nickel insertion during maturation of Escherichia coli [NiFe]-hydrogenase 3 is achieved by the metallochaperones
In this study, three synthetic zinc-chelating peptides (ZCPs) derived from sea cucumber hydrolysates with limited or none of the common metal-chelating amino-acid residues were analyzed by flame atomic absorption spectroscopy, circular dichroism spectroscopy, size exclusion chromatography, zeta-potential, Fourier transform infrared
