5-Amino-2-undecyl

Attempts to improve selectivity and sensitivity of spectrophotometric measurements by using new chromogenic reagents, e.g. of 2-(5-nitro-2-pyridylazo)-5-(A -propyl-A-sulfopropylamino)phenol for flow-injection-spectrophotometric determination of trace V in river water [3], Af-butyl-A -(sodium p-amino benzenesulfonate) thiourea to determine Pd in minerals and catalysts [4], benzeneacetaldehyde-4-hydroxy-oxo-aldoxime to determine Co in pharmaceuticals, biological materials and steels [5], 2,6-dichloroarsenazo for the determination of Bi in copper alloys [6], lV-undecyl-A-(sodium p-aminobenzenesulfonate)-thiourea to identify and determine Cu in alloy, liver and wheat [7], dimethoxyhydroxyphenylflurone for the determination of trace amounts of Mo in steel and pure iron [8] and 5-(6-methoxy-2-benzothiazole-azo)-8-aminoquinoline for the detection of Co in drainage sediment and Ni in A1 alloy [9] have recently been reported.
