2,4-Dinitrophenylhydrazine (or Brady's reagent) is a chemical compound that can be used in a chemical test to detect whether an organic compound has a C=O ( carbonyl) group. If it does, a yellow or red precipitate is formed. This precipitate is a hydrazone, containing the functional group C=N–N. Crystals of different hydrazones have precise but different melting and boiling points, hence 2,4-dinitrophenylhydrazine is used to distinguish between various compounds containing carbonyl groups. ...more on Wikipedia about "2,4-Dinitrophenylhydrazine"

9,10-Dithioanthracene is the first molecule ever to be able to walk in a straight line by itself simply by mimicking how a human walks. It is made up of a coal-tar derivative that is linked to a pair of sulfurous organic compounds. When the linked compounds were heated, they moved in alteration so that only one foot lifted from the copper surface. During testing, the molecule took about 10,000 unassisted steps. Investigators at the University of California, Riverside, and their colleagues believe the project could lead to molecular computers in which DTA or other like molecules are used as nano-abacuses. ...more on Wikipedia about "9,10-Dithioanthracene"

Azobenzene is a chemical compound composed of two phenyl rings linked by a N=N double bond. The term 'azobenzene' or simply 'azo' is often used to refer to a wide class of molecules that share the core azobenzene structure, with different chemical functional groups extending from the phenyl rings (technically, these compounds should be referred to as 'diazenes'). The azobenzene compounds strongly absorb light, and were historically used as dyes in a variety of industries. One of the most intriguing properties of azos is photoisomerization behavior between two isomers, the trans- and cis- configurations. The two isomers can be switched with particular wavelengths of light: ultraviolet light, which corresponds to the energy gap of the π-π* (S2 state) transition, for trans-to-cis conversion, and blue light, which is equivalent to that of the n-π* (S1 state) transition, for cis-to-trans isomerization. For a variety of reasons, the cis- isomer is less stable than the trans (for instance, it has a distorted configuration and breaks the aromaticity of the trans configuation). Thus, cis-azobenzene will thermally relax back to the trans via cis-to-trans isomerization. The trans isomer is more stable by approximately 50 kJ/mol, and the barrier to photo-isomerization is on the order of 200 kJ/mol. Azobenzene molecules can be incorporated into polymer matrices in order to stabilize them. It is also interesting to note that the rigid rod-like structure of azo molecules makes them behaves as liquid crystal mesogens in many materials. ...more on Wikipedia about "Azobenzene"

It can be extracted from a number of natural sources in which it occurs, such as apricot, cherry, and laurel leaves, peach seeds and, in a glycoside combined form ( amygdalin), in certain nuts and kernels. Nowadays benzaldehyde is primarily made from toluene by a number of different processes. ...more on Wikipedia about "Benzaldehyde"
