Development and Validation of a Simple and Sensitive Reverse-Phase High Performance Liquid Chromatographic Method for the Determination of Ibuprofen in Pharmaceutical Suspensions
...Show More Authors

The aim of this work was to develop and validate a rapid and low cost method for estimation of ibuprofen in pharmaceutical suspensions using Reverse-Phase High Performance Liquid Chromatography. The proposed method was conducted and validated according to International Conference on Harmonization (ICH) requirements. The chromatographic parameters were as follows: column of octyldecylsilyl C18 with dimensions (150 × 4.6) mm, mobile phase composed of acetonitrile with phosphoric acid with a ratio of 50 to 50 each using isocratic mode, flow rate of 1.5 mL/min and injection volume of 5 μL. The detection was carried out using UV detector at 220 nm. The method was validated and showed short retention time for ibuprofen peak at 7.651 min, with linearity in the studied range of 0.4 - 1.6 mg/mL (R2 = 0.9999) and with great accuracy ]percent recovery was (100.48%), percent relative error(-1.511-1.465)%[ and repeatability (RSD% = 0.112 for Retention time). The detection and quantitation limits were determined to be 0.036 and 0.110 mg/mL, respectively. This method was applied successfully to determine the content of ibuprofen in three commercial pharmaceutical products. Looking at the short time of analysis and the low limit detection, we recommend this method for routine assays in the quality control laboratories and as a good method for stability studies of ibuprofen.

The goal of the research is to identify prevailing values in Kurdish children’s stories, and statistically significant differences between groups. In the theoretical framework, the definitions of values are reviewed. Furthermore, a range of previous studies were offered, with the most important findings.
To achieve the goals of this research, an amount of 14 Kurdish children’s must be analyzed. The selected Kurdish children’s stories must be translated to Arabic conform the classification ’White’.  After confirming the stability of this tool, the researcher reached the following results:

The cognitive and physical values received the highest ratios, while the moral, practical, patriotic and nationalistic values

Synthesis of New Heterocyclic Derivatives from 4-(3, 5-Dimethyl-1-phenyl-1H-pyrazol-4-ylazo)- benzoic acid
...Show More Authors

In this work pyrazolin derivatives were prepared from the diazonium chloride salt of 4-aminobenzoic acid. Azo compounds were prepared from the reaction of an ethanolic solution of sodium acetate and calculated amount of active methylene compound namely, acetyl acetone to obtain the corresponding hydrazono derivative (1). Cyclocondensation reaction of compounds (1) with hydrazine hydrate and phenyl hydrazine in boiling ethanol affording the corresponding pyrazoline-5-one derivatives of 4-aminobenzoic acid (2,3). Then compound (3) was reacted with thionyl chloride to give the corresponding acid chloride derivative(4), followed by conversion into the corresponding acid hydrazide derivative (5) carboxylic acid thiosemicarbazide (11), esters
