A series of novel disperse azo dyes based on 2-anilinoethanol were synthesized using aniline derivatives as diazo components. These dyes have been characterized by melting points, FT-IR and 1H NMR spectroscopic methods. The effect of pH variation and solvents polarity on the absorption spectra w...
In view of the significance of glycoprotein biomarkers for early clinical diagnostics and treatments of diseases, it is essential to develop efficient and selective enrichment approaches for glycoproteins. Molecularly imprinted polymers (MIPs) have found important applications for separation and...
A high-performance liquid chromatography (HPLC) method was developed to measure levels of d-threo-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol (d-threo-PPMP) in mouse plasma and liver. d-threo-PPMP was measured by HPLC with a Luna Pheny-Hexyl column (5 μm, 250 mm × 4.6 mm) employing UV de...
Ethyl 2,4-dioxo-4-phenylbutyrate, obtained by condensation of acetophenone with diethyl oxalate, was converted to 3-oxo-3-phenyl-1-propanol in 90% yield by reaction with baker’s yeast. Reductive amination with sodium cyanoborohydride in the presence of ammonium acetate gave the racemic 3-amino-...
The single-component and competitive adsorption isotherms of the enantiomers of 3-chloro-1-phenyl-1-propanol were measured by frontal analysis. The stationary phase was a cellulose tribenzoate coated on silica, the mobile phase an n-hexane–ethyl acetate (95:5) solution. The adsorption data meas...
The Taylor–Aris chromatographic technique was employed for the determination of the diffusion coefficients of phenylmethanol, 1-phenylethanol, 2-phenylethanol, 2-phenyl-1-propanol, and 3-phenyl-1-propanol at infinite dilution in supercritical carbon dioxide from 313.16 to 333.16 K and pressures...
The rotational broad band spectra of the OH and OD isotopologues of 3-phenyl-1-propanol have been investigated by broad band free-jet absorption millimeter-wave spectroscopy in the 60.0–78.3 GHz frequency range. The spectra of the GGt and of the TGt conformers, where the three labels refer to t...
The complex conformational behavior of 3-phenylprop-2-en-1-ol (cinnamyl alcohol) and its saturated analogue 3-phenyl-1-propanol were investigated at the DFT-B3LYP/6-311G**, MP2 and MP4(SDQ) levels of theory. The unsaturated 3-phenylprop-2-en-1-ol was predicted to exist in Cg and Gg1 conformation...
A capillary electrophoresis method was developed and validated for the determination of the purity of dapoxetine with regard to the related substances (3S)-3-amino-3-phenylpropan-1-ol, (3S)-3-(dimethylamino)-3-phenylpropan-1-ol, 1-naphthol and the enantiomer (R)-dapoxetine. The separation was ba...
A toxicologic and dermatologic review of 3-phenyl-1-propanol when used as a fragrance ingredient is presented. 3-Phenyl-1-propanol is a member of the fragrance structural group cinnamyl phenylpropyl compounds. The common characteristic structural element of cinnamyl phenylpropyl materials is an ...
A huge number of new chemical derivatives of known drugs of abuse, so-called new psychoactive substances (NPS), are sold and consumed without prior preclinical and clinical testing. For assessing the elimination behaviors, determination of the kinetic constants Km and Vmax of the cytochrome P450...
General synthetic routes to 4-methyl-5-arylpyrimidines and 5-arylpyrimidines are described. 4-Benzylpyrimidine, 4-methyl-5-phenylpyrimidine, 4-(4-methoxybenzyl)pyrimidine, and 4-methyl-5-(4-methoxyphenyl)pyrimidine have been positively identified as route-specific by-products in the Leuckardt pr...
Transfer hydrogenolysis of benzyl acetate, a model reaction for CO hydrogenolysis, was achieved by ammonium formate and PdC at 20°C. Hydrogen-donating abilities of various formate salts were found to depend on the counter-ion: K+ > NH4+ > Na+ > NHEt3+ > Li+ > H+. Kinetic studies using HCOONH4...
Alcohols and amines are formylated and acetylated in the presence of Silphos [PCl3−n(SiO2)n] in ethyl formate and ethyl acetate in high to excellent yields. This procedure provides a method to separate the product by a simple filtration.
