Optical resolution methods were established for racemic 1-(1-naphthyl) ethylamine. The resolving agents were synthesized by N-derivatizing (R)-1-(1-naphthyl) ethylamine with dicarboxylic acids. Oxalic, malonic, and succinic acid derivatives were foun

The efficiency of the resolution of N -formylphenylalanine was remarkably improved using ( S )-(+)-2-benzylaminobutanol resolving agent in acetone. The efficiency of the resolution strongly depended on the quality of the solvent. Nevertheless, solvat

Optical resolution of racemic-phenylalanine through its N -formyl derivative with a 1-phenylethylamine resolving agent is an effective procedure. Differential scanning calorimetry, single crystal X-ray diffraction and optical microscopy were used in

Previously, we used positron emission tomography (PET) for studying the pharmacokinetics of rac -[ 11 C]mirtazapine in living brain. Our findings showed that rac -[ 11 C]mirtazapine has suitable properties for PET neuroimaging. However, separate stud

The method of drying resorcinol–formaldehyde (RF) gels influences the structure and gas adsorption capacity of the resulting networks as well as of their carbonized derivatives. Small angle X-ray scattering (SAXS) reveals the presence of submicrosc

Methyl-1-phenylethylamines were resolved by phenylethylamine derivatives formed with a homologous series of dicarboxylic acids. The structure of the 4-methyl-1-phenylethylamine N-(1-phenylethylamine) succinic acid monoamide diastereoisomeric salt was

Thermochemical properties of crown ether complexes have been studied by simultaneous TG-DTA (thermogravimetric analysis-differential thermal analysis) coupled with a mass spectrometer, DSC (differential scanning calorimetry) and hot stage microscopy

O,O'-di-p-toluoyl-(2R,3R)-tartaric acid (DPTTA) was investigated as supramolecular complex (SMC) forming resolving agent with three racemic alcohols (menthol, 4-methyl-2-pentanol, trans-2-iodo-cyclohexanol) by preparative scale experiments and thermo

Thermal treatment of torasemide form A resulted in several effects which were divided into five steps. These were investigated and discussed applying TG-MS and TG-FTIR with additional information derived from SEM, hot-stage and FTIR microscopy. The i
