Drug Information

MeSH：

Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)

4-(Dimethylamino)benzaldehyde Use and Manufacturing

Methods of Manufacturing

Using N, N-dimethylaniline as raw material, it can be produced by two methods. (1) Urotropine reaction generates methylene-N, N-dimethylaminobenzylamine, transposition to generate N, N-dimethylbenzylideneamine, and then hydrolyze to obtain the product. (2) React with dimethylformamide in the presence of phosphorus oxychloride. In addition, there is another laboratory preparation method, which uses N, N-dimethylaniline, sodium nitrite and formaldehyde as raw materials.

Uses

In the presence of oxygen, some bacteria, like E.coli, are able to split tryptophan into indole and alpha-aminopropionic acid. This reagent is for detecting the indole and identify the indole-positive and indole-negative microorganisms. Forms colored condensation products (Schiff bases) with pyrroles1 and primary amines.2 In the presence of oxygen, some bacteria, like E. coli, are able to split tryptophan into indole and α-aminopropionic acid.
