125-20-2, Name is Thymolphthalein, belongs to benzofurans compound, is a common compound. Quality Control of ThymolphthaleinIn an article, once mentioned the new application about 125-20-2.
The invention discloses a method for detecting beta – D – glucuronic acid neuraminidase substrate, in particular to hundreds of miles of phenolphthalein – alpha – D – glucuronic acid, its preparation method comprises the following steps: the hundreds of miles of phenolphthalein with acetyl bromide – alpha – D – glucose acid methyl ester by the reaction of the hundreds of miles of phenolphthalein – alpha – acetyl – D – glucuronic acid methyl ester, removing acetyl get hundreds of miles of phenolphthalein – alpha – D – glucuronic acid methyl ester, then the hydrolysis reaction to obtain the hundreds of miles of phenolphthalein – alpha – D – glucuronic acid. The invention hundreds of miles of phenolphthalein – alpha – D – glucuronic acid as a detecting beta – D – glucuronic acid neuraminidase substrate, has stable properties not easy to deteriorate, the advantages of sensitive coloring, and the process is simple, and the cost can be significantly reduced.
