4-Methoxy-3-(4-nitrobenzyloxy)benzaldehyde

3-Methoxy-4-(4-nitro­benz­yloxy)­benzaldehyde

In the title compound, C(15)H(13)NO(5), the vanillin group makes a dihedral angle of 4.95 (8)° with the benzene ring of the nitro-benzene group. The packing is stabilized by weak, non-classical inter-molecular C-H⋯O inter-actions which link mol-ecules into chains running along the c axis.

Evaluation of plasma 3-methoxy-4-hydroxyphenylglycol.

A high-performance liquid chromatographic (HPLC) assay suitable for the evaluation of 3-methoxy-4-hydroxyphenylglycol (MHPG) in 1-ml aliquots of plasma is presented. Preparatory steps include extraction into ethyl acetate and minicolumn chromatography. Recoveries are monitored with [3H]MHPG. The HPLC procedure utilizes a C18 column, isocratic elution and amperometric detection. The assay was ch...

Biological evaluation of 2-arylidene-4-(4- methoxy/phenoxy-phenyl)but-3-en-4- olides

A series of nine 2-arylidene-4-(4methoxy/phenoxy-phenyl)but-3-en-4-olides (I-IX) were screened against Pheretima posthuma earthworm species to assess the anthelmintic activity of the synthetic derivatives. The in vitro effects of compounds were evaluated at a concentration of 2mg/mL and time taken by the derivatives to paralyze and subsequently kill the worms was recorded. Synthetic butenolide ...

4-[(E)-(3-Chloro-4-methyl­phen­yl)imino­meth­yl]-2-methoxy-3-nitro­phenyl acetate

The title compound, C(17)H(15)ClN(2)O(5), displays a trans-configuration with respect to the C=N double bond. The mol-ecule is twisted, the dihedral angle between the mean planes of the two benzene rings being 18.70 (12)°. The nitro, meth-oxy and acetyl groups are oriented at 80.70 (11), 35.2 (2) and 72.35 (10)°, respectively, to the benzene ring to which they are bonded. The crystal structure ...
