The invention pertains to a labeled compound detectable by IR spectroscopy contains at least one histidine residue bound to a cyanate or thiocyanate metal complex that has an IR absorption band within the spectral region of 2399-1900cm. An assay reagent for simultaneously detecting or determining a plurality of different analytes in a sample is made up of a plurality of different labeled compounds, each being independently distinguishable from the others by absorbing energy in a different and distinguishable region in the range of 2300 to 1900cm.
