Time Advantage in Pharmaceutical Research: Sample Preparation with the High Energy Ball Mill Emax The development of drugs with poorly soluble to insoluble active ingredients is a big challenge for the pharmaceutical industry. The bioavailability of orally taken active ingredients, which means to what extent and in which period of time the substance is ingested by the body and is available at the place of action, strongly depends on the percentage dissolved in the gastrointestinal tract.

Introduction The first stage in the reaction between benzhydryl chloride Ia and 2- dimethylamino ethanol II is N-alkylation, followed by the formation of the amino ether III and the amino alcohol IV in a ratio depending on the reaction temperature d.
In the literature the "ether" VI is described as a solid; it has been subjected to pharmacological testing 8 - 10but in these pharmacological reports no synthetic details or physical constants have been given.
Table l lists the compounds and conditions employed so far in the synthesis of compound VI as well as the physical constants reported. For VII those data are given in Table 2.

Reactions between benzhydryl chloride and 2-aminoethanol. Reaction conditions and results in the synthesis of compound VI.
Reaction conditions and results in the synthesis of compound VII. After isolation it was identified as the JV-benzhydryl benzhydryloxy ethylamine VIII by means of a separate synthesis. Reaction conditions and yields of several compounds.
The NMR spectrum of this salt showed that the signals of the ortho protons are more downfield than those of the meta and para protons. The central proton 5 exhibits a tripiet, whichwaschanged into a singlet after treatment with deuterium oxide. The relevant data are collected in Table 4. The results are listed in Table 5.
The reaction of Ia with V or its corresponding sodium compound is accompanied by N- and O-alkylation.
Synthesis of VI, in the manner reported Yield 28 per cent based on 2-aminoethanol. After cooling the reaction mixture was extracted with chloroform. Anhydrous ether was used to precipitate compound VIII as the hydrochloride, which was recrystallized from water and washed with ether.
Yield 38 per cent. Extraction with ether, evaporation of the ethereal extract and crystallization of the residue from 2-propanol afforded the free base. Purification of VII, by dissolving the alkaline reaction products in petroleumether b.Geschiedenis. Het bedrijf werd in als coöperatieve apothekersvereniging onder de naam Onderlinge Pharmaceutische Groothandel (OPG) opgericht.
White Paper Sieve Analysis - Different methods for a variety of applications The determination and knowledge of the particle size distribution is an essential part of the quality control process for industrial products. Products Chromatography Liquid chromatography in combination with mass spectrometry (LC-MS) is an essential tool in the analysis of biological samples, especially in proteomics, metabolomics and other systems biology areas.
PharmaFluidics introduces the silicon revolution in chromatography. The perfect order of the micro-Chip Pillar Arrays overcomes the physical limits of any packed bed alternative. The revolutionary redesign of the HPLC separation bed reduces peak dispersion to an absolute minimum.
