Application

3,5-Dimethylphenol was used in simultaneous determination of urinary concentrations of phenol, o-, p-, m-cresols, 1-, 2-naphthol and xylenol isomers by capillary gas chromatography. It was used as starting reagent for total synthesis of landomycin A, most potent antitumor angucycline antibiotic and optically active polypropionate units.

Optically active polypropionate units were synthesized in 9-11 steps from 3,5-dimethylphenol. The sequence consists of the Buchner reaction controlled by a chiral 2,4-pentanediol tether and diastereoselective hydrogenation over Raney nickel. [reaction: see text]

A strategy for the determination of the presence of thiol-containing amino acids was successfully established by simply assembling copper chloride and xylenol orange (3,3'-bis[N,N-bis(carboxymethyl)aminomethyl]-o-cresolsulfonephthalein trisodium salt; XO) in a 1 : 1 molar ratio in quasi-physiological water solution (pH 6.0).

Natural oxidation is an undesirable process suffered by gel dosimetry systems as it changes the values and spatial distribution of absorbed doses. Natural oxidation of Fricke xylenol gel (FXG) dosimeter was inferred from optical absorbance values measured for the first

The ferrous oxidation in xylenol orange version 2 (FOX2) assay coupled with triphenylphosphine has recently been employed for the measurement of total plasma hydroperoxides (ROOHs). In this study, we have evaluated sample handling and the effect of storage conditions on

In recent years, magnetic-resonance imaging of gelatin doped with the Fricke solution has been applied to the direct measurement of three-dimensional (3D) radiation dose distributions. However, the 3D dose distribution can also be imaged more economically and efficiently using the
