1.A gas-liquid chromatographic (GC) method for the analysis of butriptyline in serum has been developed. Quantitation is based on the peak height ratio between butriptyline and promazine used as internal standard. A triple partition provides a “clean” extract. A detection limit of 10 ng/ml is ...

RésuméLe Biclotymol*** a été étudié vis-à-vis de souches de staphylocoques, de streptocoques et d'Haemophilus isolées en situation pathogène. Non bactéricide sur les streptocoques en 24 h, même à 100 mcg/ml, il l'est souvent sur les staphylocoques en 10 mn entre 20 et 80 mc...

The melt from the usual monoclinic phase (Phase I) of biclotymol (TfusI = 400.5 ± 1.0 K, ΔfusHI = 36.6 ± 0.9 kJ mol−1) recrystallizes into another phase, Phase II, that melts at TfusII = 373.8 ± 0.2 K (ΔfusHII = 28.8 ± 1.0 kJ mol−1). The transformation of Phase II into Phase I is found to ...

The present case study focuses on the crystallization kinetics and molecular mobility of an amorphous mouth and throat drug namely Biclotymol, through differential scanning calorimetry (DSC), temperature resolved X-ray powder diffraction (TR-XRPD) and hot stage microscopy (HSM). Kinetics of crys...

This study investigates for the first time the thermodynamic changes of Biclotymol upon high-energy milling at various levels of temperature above and below its glass transition temperature (Tg). Investigations have been carried out by temperature modulated differential scanning calorimetry (TM-...

We employ dielectric spectroscopy to monitor the relaxation dynamics and crystallization kinetics of the Biclotymol antiseptic in its amorphous phase. The glass transition temperature of the material as determined by dielectric spectroscopy is Tg = 290 ± 1 K. The primary (α) relaxation dynamic...

The electrodeposition behaviors of nickel on glassy carbon (GC) and carbon steel (CS) electrodes were investigated in the 14.3%–85.7% (mole fraction) betaine·HCl–ethylene glycol (EG) ionic liquid using cyclic voltammetry and chronoamperometry. The results indicated that the reduction of Ni(II...

The multidentate compound, tris-(o-tbutylthiobenzyl)-aminoethylamine (L4), which contains four nitrogen and three sulfur donors has been synthesised by combining 2-amino-methyl-1,3-diamino-propane (tren) with o-tbutylthiobenzaldehyde. L4 has been reacted with the nitrate salts of nickel, copper ...

In this study, carbon paste electrode (CPE) modified with NiO/SWCNTs and 1-butyl-4-methylpyridinium tetrafluoroborate (1B4MPTFB) was used for the effective determination of raloxifene as a sensor. The use of NiO/SWCNTs and 1B4MPTFB in the electrode matrix showed great conductivity for electro-ox...

The unexpectedly aqueous stable bis-tellurium cationic complex [Co(dmgH)2{PhTe(CH2)3SO3Na}2]+(1+) (dmgH− = dimethylglyoximate) has been fully characterized in the solid state and in solution. The UV–Vis spectrum of 1+ differs from that of earlier cobaloximes, exhibiting a new low energy band ce...

A novel, cheap, reliable water based precursor ink has been used for the large scale production of amorphous cobalt sulfide (CoS) on fluorine doped tin oxide (FTO). The method uses a metal–organic complex of Co(II) and thioglycolic acid (TGA), it is cheap and easy to prepare. The electrodes pre...

The coordination chemistry of the metalloligand [Pt2(μ-S)2(PPh3)4] towards cobalt(II) and cobalt(III) centres has been explored using an electrospray ionisation mass spectrometry (ESI MS)-directed methodology. Reaction of [Pt2(μ-S)2(PPh3)4] with CoCl2·6H2O in methanol gave a green-yellow susp...

Conversion of CO2 into value-added chemicals by solar energy is one of the most promising pathways to partially address both energy crisis and global warming effect. The properties of reaction medium play a key role in determining the efficiency of CO2 photoreduction and modulating the distribut...

Reductive dechlorinations are especially promising reactions for improving the biodegradability and hence decreasing the environmental impact of chlorinated organic pollutants.
