2-Hydroxy-3-methoxybenzaldehyde 2,4-dinitrophenylhydrazone pyridine monosolvate
The Schiff base molecule of the title compound, C(14)H(12)N(4)O(6)·C(5)H(5)N, was obtained from the condensation reaction of 2-hy-droxy-3-meth-oxy-benzaldehyde and 2,4-dinitro-phenyl-hydrazine. The C=N bond of the Schiff base has a trans arrangement and the dihedral angle between the two benzene rings is 3.49 (10)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, ...

Multicellular Tumor Spheroid (MTS) represents a three-dimentional structural form of tumors in laboratory conditions, and it has the characteristics of avascular micrometastases or intervascular spaces of big tumors. Recent studies indicate that extracellular matrix (ECM) proteins play a critical role in tumor metastasis, therefore normal and cancer cells require an ECM for survival, proliferat...

There is a dearth of information on the prevalence and clinical characteristics of adult polycystic kidney disease (APKD) in Nigeria. Earlier studies in the tropical developing countries have reported either the rarity or very low prevalence of this disease and more importantly as a cause of renal failure, but there are hardly any such studies focussing on the pattern of APKD in renal disease p...
متن کاملDirect Spectrophotometric determination of Aluminum (III) using 5-Bromo-2-hydroxy-3-methoxybenzaldehyde-P- hydroxybenzoic hydrazone
Highly sensitive and selective direct spectrophotometric method is proposed for the determination of aluminium in various real samples. 5-Bromo-2-hydroxy-3-methoxybenzaldehyde-phydroxybenzoic hydrazone reacts with Al(III) forming yellow coloured soluble complex in aqueous dimethyl formamide which has a λmax at 390 nm in the pH range 3.0-7.0. The system obeyed Beer’s law in the range 0.053 – 0.7...
متن کاملDirect Spectrophotometric Determination of Ni (II) Using 5- Bromo-2- hydroxyl -3-methoxybenzaldehyde-4-hydroxy benzoichydrazone
: A rapid, simple,sensitive and selective direct spectrophotometric method has been developed for the determination of nickel(II) in various real samples. 5-Bromo-2-hydroxy-3-methoxy benzaldehyde-p-hydroxybenzoic hydrazone reacts with Ni(II) forming green coloured soluble complex [ ( Ni(II)-5-BHMBHBH] in basic buffer solution. The maximum absorbance was observed in the pH range 5.5-7.5 and Ni(I...
