Studies on the metabolism in plants (4, 5, 6, 8) aInd in soil (1, 2) of the herbicide propanil (3,4-dichloropropionanilide) have showin that the parent compound is rapidly hydrolyzed to release 3,4-dichloroaniline (DCA). In plants, the aniline moiety is recovered in several compounds including sugar and lign,in conjugates (6, i7), while in soil the major product is an azo compound identified as...

Development of an analytical method to determine Recorcinolcompound by coupling reaction for diazotized solution 4- aminacetphenone in the presence buffer NasHPO, (pH= 10.8) give acompound with a single azo dye salt having orange color soluble waterwith high absortivity at wave length 449 nm , early study have aperfect optimum condition was made determination. A calibrationcurve range concentra...

Since Miller and Miller first published their classic paper on the protein-bound azo dye in the liver of animals subjected to this type of experi mental carcinogenesis (7), many observations have accumulated to correlate this aspect of the process with the carcinogenicity of the particular azo dye (8, 9). Recently, Griffin and co-workers (5) have shown that removal of the pituitary gland blocks...

A novel of Chemosensor compound 4-((E)-(2-(2,4-dinitrophenyl) hydrazineylidene) methyl)-2-methoxy-6-((E)-phenyldiazenyl)phenol has designed and synthesized from 2,4-dinitrophenyl hydrazine (E)-4-hydroxy-3-methoxy-5-(phenyldiazenyl)benzaldehyde. This sensor was applied as a colorimetric for recognition cyanide anion in acetonitrile solution. In the presence ion, solution turned bright yellow to ...

In the first report (1) of this series, we described a spectroscopic method for the determination and differentiation of the azo dyes resulting from coupling of arsanilic acid and related compounds with tyrosine and histidine. The bisazo compound of tyrosine and the bisazoamino compound of lysine were also characterized. In the second paper (2) we showed that the spectroscopic method can be app...
