The title compound, 2C(7)H(6)NO(4) (+)·2Cl(-)·C(3)H(6)O, crystallizes with two 2,6-dicarboxy-pyridinium cations, two chloride anions and one acetone mol-ecule in the asymmetric unit. The crystal structure is characterized by alternating cations and by Cl(-) anions, forming zigzag chains running along the a axis.

Here in the current research work we have developed newer method for synthesis of diferuloyl methane(curcumin)Ca-q. MangnesiumHydroxide were found to be an effective and mild base curcumin its derivatives obtained by reaction one equivalent acetyl acetone with two corresponding aromatic aldehyde microwave(240 W). The existingscheme offers severalaids such as high yield, less time, environmental...

The purpose of this study was to evaluate the histopathological effect of eugenol and bis-eugenol on oral mucous membranes at the tissue organ level. Oral mucous membranes of mice were applied with three reagents, eugenol, bis-eugenol, and acetone (as the control). The control group showed a normal architecture. The eugenol group showed severe hyperkeratosis, parakeratosis, cellular edema, patc...

An indole hydrazone has successfully been synthesized employing Schiff base reaction conditions starting from 4,6-dimethoxy-2,3-diphenylindole-7-carbaldehyde with hydrazine hydrate. The of this compound acetone yielded based imine compound. structure targeted was identified by mass and 1H spectroscopy along single crystal X-ray diffraction technique. Also, bromination bis-indole N-bromo succini...

The biosynthetic utilization of laccase/mediator system is problematic because the use of organic cosolvent causes significant inhibition of laccase activity. This work explored how the organic cosolvent impacts on the laccase catalytic capacity towards 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) in aqueous solution. Effects of acetone on the kinetic constants of laccase were ...

In this paper, a simple dispersive liquid-liquid microextraction for the extraction and pre-concentration of formaldehyde in seawater samples followed with spectrophotometric is proposed. Formaldehyde was derivatized in situ with acetyl acetone in the presence of ammonium acetate in a single step. Then it was collected into a mixture of ethanol (disperser solvent) and chloroform (extracting...
