Milling Red SWB l-[4-[4-[4-toluenesulfonyloxy]phenylazo](3,3 dimethyl-l,l -biphenyl)-4 -azo]-2-hydroxynaphthalene-6,8-disulfonic acid di-Na salt, Acid Red 114 [6459-94-5] M 830.8, m dec >250", Cl 23635, X,max 514nm. Salted out three times with sodium acetate, then repeatedly extracted with EtOH. [McGrew and Schneider J Am Chem Soc 72 2547 1950.] See Solochrome Violet R on p. 352 in Chapter 4. 

Milling Yellow G [51569-18-7]. Salted out three limes with sodium acetate, then repeatedly extracted with EtOH. [McGrew and Schneider J Am Chem Soc 72 2547 1950.] See Solochrome Violet R on p. 352 in Chapter 4. 

Solochrome Violet R [2092-55-9] M 367.3. Converted to the monosodium salt by pptn with sodium acetate/acetic acid buffer of pH 4, then purified as described for Chlorazole Sky Blue FF. Dried at 110°. It is hygroscopic. [Coates and Rigg TFS 57 1088 1961],... 

Solochrome Violet R [4-hydroxy-3-(2-hydroxynaphthyl-l-ylazo)benzenesulfonic acid] [2092-55-9] M 367.3, Cl 15670, Xmax 501nm, pK 7.22 (OH), pK 13.39 (OH). Converted to the monosodium salt by pptn with NaOAc/AcOH buffer of pH 4, then purified by pptn of the free acid from aq soln with cone HCl, washing and extracting with EtOH in a Soxhlet extractor. The acid ppted on evaporating the EtOH and was reconverted to the sodium salt.as described for Chlorazole Sky Blue FF. Dried at 110°. It is hygroscopic.

Salt it out three times with sodium acetate, then repeatedly extract it with EtOH. See Solochrome Violet R in Aromatic compounds . Chapter 4. [McGrew Schneider J Am Chem Soc 7 2 2547 7950.]... 

Another variation involves the stripping or electrolysis of species that have spontaneously adsorbed on the surface of an electrode without the preelectrolysis step. This technique, called adsorptive stripping voltammetry, can be applied, for example, to sulfur-containing species, organic compounds, and certain metal chelates that adsorb on Hg and Au (74, 81). Examples include cysteine (and proteins that contain this amino acid), dissolved titanium in the presence of the chelator solochrome violet RS, and the drug diazepam. The amounts found by this method would necessarily be limited to monolayer levels. However, similar approaches can be employed with thicker polymer layers that can interact with solution species. Related experiments are described in Chapter 14.
