What is p-Dimethylaminobenzaldehyde?
p-Dimethylaminobenzaldehyde is an organic intermediate, which can be prepared from N,N-dimethylaniline and DMF. It has been reported that p-dimethylaminobenzaldehyde can be used to prepare high-purity DAST source powder, and can also be used to make color-developing solution to analyze semicarbazide.
4-Dimethylaminobenzaldehyde is a sort of benzaldehyde with dimethylaminobenzaldehyde at setting 4.
Kovac’s indole reagent is a remedy of 4 – (dimethylamino) benzaldehyde as well as hydrochloric acid in n-butanol.
Kovac’s reagent detects indoles as well as helps identify indole positive and indole adverse bacteria. In the visibility of tryptophan enzyme, E. coli can break down tryptophan into indole and also α-Aminopropionic acid. The p-aminobenzaldehyde in the reagent reacts with indole to develop cherry red complex, which is soluble in ethanol, ether and chloroform. It is suggested to use glucose free medium as well as peptone with high tryptophan web content for screening.
p-Dimethylaminobenzaldehyde Uses
- Dye intermediates and analytical reagents. p-Dimethylaminobenzaldehyde is used for the determination of indole, skatole, uridine, tryptophan and ergot alkaloid, etc. It is also used to distinguish serum rash and scarlet fever.
- In terms of dyes, p-Dimethylaminobenzaldehyde can be used to synthesize pressure sensitive dyes. Also used in the production of cationic brilliant red G (C.I.BasicRed52). It can also be used as a dye intermediate; as a reagent and chromatographic analysis reagent for the determination of urobilin, indole, alkaloids, etc.
- Determination of indole, skatole, urine blue mother, tryptophan, albumin, hydrogen peroxide, arsine sodium amine, anthranilic acid, antipyrine ergot alkaloid, etc., p-Dimethylaminobenzaldehyde is also used to distinguish serum rash and scarlet fever.
- Manufacture of dyes.
- p-Dimethylaminobenzaldehyde is used as a reagent for the detection of amino acids, peptides, amines, indole, hydrazine, hydrogen peroxide, anthranilic acid, antipyrine and ergot alkaloids; used as a chromogenic reagent for tryptophan; used in Detection of tryptophan in proteins; test reagent for the identification of indole-producing microorganisms; reacts with pyrroles and primary amines to form colored condensation products (Schiff bases).
- p-Dimethylaminobenzaldehyde, also known as Euclid/E reagent, is mainly used for the identification of Enterobacteriaceae, non-fermentative bacteria, fastidious bacteria, and anaerobic bacteria, and for the detection of indole derivatives and amines.

Application 1
CN201410570172.2 discloses a high-yield and high-purity DAST source powder synthesis process. The synthesis process is divided into two steps:
- Take dehydrated alcohol as solvent, carry out the reaction of 4-picoline and methyl p-toluenesulfonate, prepare the dehydrated alcohol solution of 4-methyl-N-picoline p-toluenesulfonate;
- Using absolute ethanol as a solvent, under the catalysis of di-n-butylamine or piperidine, through the reaction of 4-methyl-N-methylpyridine p-toluenesulfonate and p-dimethylaminobenzaldehyde, it can be Obtain DAST source powder with high yield of 85-95% and high purity of 90-95%.
Anhydrous ethanol is used as the reaction solvent, which avoids the harm of toluene, methanol and other toxic and harmful solvents to the operator’s body, and also reduces the pollution of waste liquid to the environment; the successful research and development of the present invention is conducive to the cultivation of high-quality, large-size DAST The crystals have laid a good material and theoretical foundation for the research of DAST crystals and related products.
Application 2
CN201210035819.2 discloses the analysis method of semicarbazide in plutonium solution after separation of uranium and plutonium, comprising the following steps:
- p-Dimethylaminobenzaldehyde is dissolved in ethanol solvent to prepare a color developing solution;
- Dilute the plutonium solution by 10 to 1000 times (pH value is -0.2 to 1) after separating the uranium-plutonium containing semicarbazide with nitric acid, and add the solution to be tested diluted with nitric acid into the color developing solution;
- At a temperature of 15 to 30° C., the color developing system of step 2 undergoes a color developing reaction for at least 5 minutes;
- Using the blank solution as a reference, measure the absorbance value A of the color developing system at a wavelength of 430-490 nm;
- According to the measured absorbance value A, combined with the concentration-absorbance value relationship curve of semicarbazide in the color developing system, the solution can be solved.
The method of the invention is simple and convenient, and does not require special instruments; and the measured values obtained by the method are in good agreement with the theoretical calculated values.
