Fast red

Uses. (9-Nitrochlorobenzene is used in the synthesis of azo dye intermediates such as o-chloroaniline (Fast YeUow G Base), i9-nitroani1ine (Fast Orange GR Base), o-anisidine (Fast Red BB Base), o-phenetidine, and (9-aminophenol (see Azo dyes). It also is used in corrosion inhibitors, pigments, and agriculture chemicals. -Nitrochlorobenzene is used principally in the production of intermediates for azo and sulfur dyes. Other uses include pharmaceuticals (qv), photochemicals, mbber chemicals (qv), and insecticides (see Insectcontroltechnology). Typical intermediates manufactured from the para isomer are -lutioaruline (Fast Red GC Base), anisidine, -aminophenol, -nitrophenol, -phenylenediamine, 2-chloro-/)-anisidine (Fast Red R Base), 2,4-dinitrochlorobenzene, and l,2-dichloro-4-nitrobenzene. 

Uses. (9-Nitrotoluene is used in the synthesis of intermediates for azo dyes, sulfur dyes, mbber chemicals, and agriculture chemicals. Typical intermediates are o-toluidine, o-nitrobenzaldehyde, 2-nitro-4-chlorotoluene, 2-nitro-6-chlorotoluene, 2-amino-4-chlorotoluene (Fast Scarlet TR Base), and 2-amino-6-chlorotoluene (Fast Red KB Base). -Nitrotoluene is used principally in the production of intermediates for azo and sulfur dyes. Typical intermediates are -toluidine, -nitrobenzaldehyde, and 4-nitro-2-chlorotoluene.

With Orange I [574-69-6] (34) (Cl Acid Orange 20 Cl 14600) the naphthalene moiety was iatroduced to azo chemistry. Basacid Red 340 [1658-56-6] (35) (Cl Acid Red 88 Cl 15620) the first red azo dye of technical value was discovered by BASF ia 1876. Its previous name was Fast Red AV and it is stiU produced ia large amounts ia the United States because of its low cost and good dyeiag and fastness properties. This dye became the prototype of a large number of red azo dyes that were developed simultaneously with the iatroduction of new derivatives of naphthalene. 

In the same way acetoacetarulides and pyrazolones can be used as coupling components. Larger molecules can be formed in the pigment series by using a benzidine derivative as the middle component as, eg, in Vulcan Fast Red B [6358-87-8] (141) (Cl Pigment Red 38 Cl 21120).

Bacterial cells of Oenococcus oeni incubated for 48 h with three azo dyes (Fast red, Fast orange, and Methanil yellow) gave rise to decolorization due to adsorption, from 68% with Fast red to 30% with Fast orange and Methanil yellow [41]. Ozdemir et al. [44] observed a 93.9% decolorization of Acid Black 210 within 24 h by Vibrio harveyi TEMS1, a bioluminescent bacterium isolated from coastal seawater in Turkey. After extraction in methanol of biomass, the major part of the decolorized dye was recovered, indicating that decolorization was mainly due to...

Morken and co-worker (57) recently reported using a visual colorimetric assay to evaluate a variety of catalyst systems for allylic alkylation. This method uses the reaction of naphthol with Fast Red diazonium salt as a method for determination of catalyst activity. Reaction of the naphthyl allyl carbonate (222) with palladium gives the naphthoxide (223) after loss of C02. The naphthoxide then deprotonates... 

The chemical synthesis of linear turns-quinacridones and their substituted derivatives that have been marketed subsequently is a complicated multi-stage sequence, making such pigments very expensive and sustainable only where high-fastness red pigments are essential, as in the car industry. There are four routes of synthesis, details of which have been given by Pollack [27]. 

Convenient ready-to-use nuclear counterstains in blue, green or red colour like Hematoxylin, Methyl Green and Nuclear Fast Red are available from Vector Laboratories (http //www.vectorlabs.com/), DAKO (http //www.dako.com/) and some other vendors, but if you are interested in preparing nuclear counterstains yourself, good and thorough procedures may be found in textbooks of Polak and Van Noorden (1997) and Renshaw (2007) or on the website http //www.ihcworld. com/counterstain solutions.htm. 

These studies were followed up by Ciba-Geigy and systematically developed into a synthetic route to a group of very fast red pigments, known as diketo-pyrrolopyrrole pigments (DPP pigments) [3, 4], since the brilliant red crystals of 141 turned out to be extremely insoluble.

Alkaline phosphatase acts on many substrates as well, each precipitating as a different color. For example, a combination of 5-bromo-4-chloro-3-indolyl phosphate (BCIP) and nitro blue tetrazolium (NBT) results in a permanent blue precipitate at the site of alkaline phosphatase localization. There are other compounds that can also be tried, such as Fast Red TR/Naphthol AS-MX (Sigma, St. Louis, MO), which precipitates as a red color.
