General description

1-Naphthol is the hydroxyl derivative of naphthalene. It forms hydrogen bonded complexes with H2O, CH3OH, NH3 and ND3 in gas phase. Hydrogen-bond dissociation energy of these complexes has been evaluated. Its sorption by biochars (obtained from orange peels, having pyrolytic temperatures in the range of 150-700°C and designated as OP150-OP700) has been studied. It has been identified as an impurity in the active pharmaceutical ingredient (API) of duloxetine hydrochloride.

Application

1-Naphthol (Naphthalen-1-ol) may be used as a standard for the NMR, FT-IR and mass spectrometric characterization of impurities present in the Duloxetine Hydrochloride active pharmaceutical ingredient (API).3

Biochars, derived from biomass, are increasingly recognized as an environmental-friendly sorbent to abate organic pollutants. Sorption variations of biochars with their pyrolytic temperatures are evaluated. Nine biochars of orange peels with different pyrolytic temperatures (150-700 degrees C, referred as OP150-OP700)

Guanosine derivatives are important for diagnosis of oxidative DNA damage including 8-hydroxy-2'-deoxyguanosine (8-OHdG) as one of the most abundant products of DNA oxidation. This compound is commonly determined in urine, which makes 8-OHdG a good non-invasive marker of oxidation stress.
