The title compound, C27H27N5O3 H2O, is built up from pyrazolinone, phenyl and acetophenone oxime moieties. The 2-phenyl substituent is nearly perpendicular to the pyrazolinone ring, with a dihedral angle of 87.66 (1) . The acetophenone oxime moieties are twisted out of the pyrazolinonering plane by 47.04 (1) . The molecules in the crystal pack in an antiparallel fashion and are held together by...

Facile modification of oligodeoxyribonucleotides is required for efficient immobilization to a pre-activated glass surface. This report presents an oligodeoxyribonucleotide which contains a hairpin stem-loop structure with multiple phosphorothioate moieties in the loop. These moieties are used to anchor the oligo to glass slides that are pre-activated with bromoacetamidopropylsilane. The effici...

An analytical method for lignins has been developed that involves derivatization followed by reductive cleavage (DFRC), depolymerization, and quantitative (31)P NMR spectroscopy. This technique detects and quantifies the various ether linkages present in softwood residual kraft lignins (RKL) and milled wood lignins (MWL). In addition, the technique supplies new quantitative information about be...
