These compounds can be accessed through biarylation of nitroaryls followed by diazotization
NOS activity assay is based on the diazotization
of sulfanilic acid by N[O.

Fischhach  determined sulpha-drugs in aqueous solution by diazotization
with sodium nitrite in presence of acid, using p-dimethylaminobenzaldehyde as internal indicator.
The absorbance of the chromophore formed during diazotization
of the nitrite with sulphanilamide and subsequent coupling with N-1-naphthylethylene diamine dihydrochloride was measured at 546 nm and percentage scavenging activity was measured with reference to standard.
Methods: Partially purified Amaranthus spinosus leaf oxalate oxidase was immobilized through diazotization
onto arylamine glass beads affixed on the surface of a plastic strip by a non reactive fixative and employed for oxalate determination in urine and serum samples collected from healthy individuals and urinary stone formers.
3]-N concentrations (by diazotization
following hydrazine reduction) were measured on a Technicon AutoAnalyzer II system (Blakemore et al.
of the amine produces a diazonium intermediate that is not isolated but is reduced with tin chloride to the corresponding hydrazine.
Nitrite level was determined by using diazotization
The absorbance of chromophore formed during diazotization
of nitrite with sulfanilamide and subsequent coupling with naphthalene diamine was read at 546 nm.
We isolated the dimer 5 and the trimer 6 by LAH-mediated diazotization
of the corresponding biphenyls.
4,4,4- trichloro-3-oxo-2-(phenyl-hydrazono)-butyric acid ethyl ester 2 was prepared by diazotization
of required primary amine is diazotized with sodium nitrile and HCl mixture at 0-5 and it is coupled with ethyl 4,4,4-trichloro-3-oxobutanoate and afforded phenyl diazonium aceto acetic ester
