A spectrophotofluorometric method is described for the determination of tyrosine in blood dried on filter paper discs. It has been found that by immersing the paper disc containing the dried blood in aqueoustrichioracetic acid, the blood proteins remain bound to the paper and the amino acid is eluted into the aqueousphase.This method of assay is based on the principle that tyrosine reacts with ...

Naphthalene (CAS Registry Number: 91-20-3) is a natural constituent of coal tar, comprising approximately 11% of that material by weight (HSDB, 2003). It is present in gasoline and diesel fuels. All pesticide registrations of naphthalene, including use as a moth repellent, were cancelled in California in 1991 due to data gap inadequacies. However, naphthalene is included on a list of "inert" or...

Determination of carbamate pesticides such as carbaryl, carbofuran, propoxur and bendiocarb was demonstrated on a microchip with newly designed microchannels developed for efficient solvent extraction. The pesticides were hydrolyzed to corresponding naphthols, coupled with p-nitrobenzenediazonium fluoroborate reagent, and then extracted into 1-butanol as colored azo derivatives and detected wit...

Copper(I) and copper(II) 1,5-diaza-cis-decalin complexes [(N2)Cu] are effective precatalysts for aerobic oxidative coupling of naphthol substrates. Mechanistic studies, however, reveal that these complexes are not the reactive form of the catalyst under steady-state conditions. Rather, the active catalyst forms in a presteady-state self-processing step that involves oxygenation of the naphthol ...
