Environmental and breathing zone samples were analyzed for 3,3'- dichlorobenzidine (91941) (DCB) and ortho-dianisidine (119904) (ODA) at Harshaw/Filtrol (SIC-2865), Louisville, Kentucky in August, 1984. (cdc.gov)
Amylase was assayed measuring the maltose produced by the breakdown of starch and peroxidase with ortho dianisidine. (usp.br)
Benzidine2
Benzidine condensed with acetophenone and benzophenone to form the corresponding di-anils, o-tolidine reacted similarly with acetophenone but not with benzophenone, and o-dianisidine did not react with either acetophenone or benzophenone. (gla.ac.uk)
Benzoin reacted with benzidine, o-tolidine and o-dianisidine to form didesyl-derivatives, which in contrast to the di-anils, were extremely resistant to hydrolysis. (gla.ac.uk)
Peroxidase2
o-Dianisidine is also used in assaying activity of peroxidase in lab. (wikipedia.org)
ce {Peroxidase}}]{ROH}+R'OH}}} Where the ROOR' can be hydrogen peroxide, and the electron donor be o-dianisidine. (wikipedia.org)
Dyes2
o-Dianisidine is a precursor to some azo dyes by formation of the bis(diazonium) derivative, which is coupled to diverse aromatic compounds. (wikipedia.org)
Some commercial dyes derived from o-dianisidine include C. I. Direct Blue 1, 15, 22, 84, and 98. (wikipedia.org)
Myeloperoxidase was solubilized with hexadecyltrimethylammonium bromide and myeloperoxidase activity was measured with a dianisidine-H2O2 assay. (nih.gov)
