Definition
ChEBI: Celestin blue B is an organic chloride salt composed of 1-carbamoyl-7-(diethylamino)-3,4-dihydroxyphenoxazin-5-ium and chloride ions in a 1:1 ratio. A histological dye used in solution with an iron alum mordant as a hematoxylin substitute in the H&E stain. It has a role as a fluorochrome and a histological dye. It contains a Celestin blue B(1+).
Preparation
excessive amounts of ?N,N-diethyl-4-nitrosobenzenamine or N,N-diethyl-4-(phenyldiazenyl)benzenamine?and 3,4,5-Trihydroxybenzamide reaction.
Synthesis
In an enamelled 6000 L ket tle equipped with a wooden gate stirrer, 110 kg of gallamide and 2000 L of alcohol (denatured, 94 %) are brought to a rapid boil. Over 10 h, 240 kg of nitrosodiethylaniline hydrochloride, dissolved in 1500 L of ethanol, is allowed to flow in. After addition of 21 kg of potassium carbonate, the reaction mixture is boiled for an other 1 h and allowed to cool to 20 ℃; 40 L of 20 % hydrochloric acid is added, and the mix ture is pressed into asuctionfilter withafiltering stone bottom. After stirring with 500 L of 20 % hydrochloric acid, the mixture is filtered under suction until the product is well dried, and the product is further dried at 70 ℃. Yield: 95 %. The ethanol is recovered by distillation.
Properties and Applications
