Transition metal complexes of benzopyran-4-one Schiff bases
ISBN: 9783659681721 / Angielski / Miękka / 2015 / 176 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The condensation of primary amines with aldehydes or ketones gives products known as imines or Schiff bases which contain a C=N group. Metal complexes of Schiff bases have contributed widely to the inorganic chemistry of chelate system. The extreme sensitivity of physical and chemical properties of Schiff base compounds to small changes in the substitution and in the environment, together with their ready availability justify their extraordinary wide spread applications. The chelating properties of Schiff bases towards transition metal ions were of interest to many authors. The Schiff bases...

La, Nd and Er complexes of Schiff bases derived from benzopyran-4-one
ISBN: 9783659488436 / Angielski / Miękka / 2013 / 240 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Schiff bases have played an important role in the development of coordination chemistry. The growing importance of the Schiff bases in modern coordination chemistry is attributable to recent observations about their antibacterial and antifungal properties. Lanthanide coordination compounds are the subject of intense research efforts owing to their unique structures and their potential applications. Accordingly, this book contains preparation and characterization of a series of Schiff bases derived from the condensation of benzopyran-4-one derivatives with aliphatic diamines (ethylenediamine...

Spectrophotometric determination of diaveridine and two sulfa drugs
ISBN: 9783659754753 / Angielski / Miękka / 2015 / 192 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Analytical chemistry is very important in pharmaceutical industries, where without quality assurance, the pharmaceutical preparations cant be performed. Thus, the analyst needs a rapid, easy, inexpensive, sensitive, selective and accurate method of analysis, these properties can be achieved by the use of spectrophotometery for quantitative analysis of pharmaceutical compounds. Several spectrophotometric methods are in use in pharmaceutical analysis. For a long time direct UV-measurements have been used as the official and pharmacopoeias methods. Spectrophotometric methods applied in...

Spectrophotometric Determination of Amiodarone Hydrochloride
ISBN: 9783659780110 / Angielski / Miękka / 2015 / 136 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Spectrophotometry is an instrumental method of analysis that widely adopted where spectrophotometric methods of analysis are still in competition with other techniques applied for pharmaceutical analysis. Because of the lack of specific methods for the determination of amiodarone hydrochloride in the literature, it is worthy to investigate some other methods for its determination and the adaptation of these methods to be available for pharmaceutical preparations. So, the present work aims to develop new simple, accurate and sensitive spectrophotometric methods for the quantitative...
