1,3-Diethyl-1,3-diphenyl-urea.

Acta Crystallogr. Sect. E Struct. Rep. Online 67(4) , o827-o827, (2011)

The mol-ecule of the title compound, C(17)H(20)N(2)O, a symmetrical derivative of urea, shows non-crystallographic C(2) symmetry. Inter-action with the aromatic system of the phenyl substituents as we...

Photochemically induced fluorescence studies of 1,3-diethyl-1,3-diphenylurea as stabilizer and its quantitative determination.

Forensic Sci. Int. 240 , 35-40, (2014)

The photochemically induced fluorescence (PIF) studies of 1,3-diethyl-1,3-diphenylurea or ethyl centralite (EC) as stabilizer have been carried out under various conditions. Influences of solvent type...

New protocol for the isolation of nitrocellulose from gunpowders: utility in their identification.

Talanta 81(4-5) , 1742-9, (2010)

In this work, a new approach for the isolation of nitrocellulose from smokeless gunpowders has been developed. A multistep solvent extraction method was needed to purify nitrocellulose contained in gu...
