71077-14-0 - Introduction
4,5-Dihydro -5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid is an organic compound often abbreviated as "pyrazole red". The reaction products thereof with N,N'-bis (mixed phenyl, tolyl and xylyl) guanidine hydrochloride derivatives can be a variety of substances, depending on the reaction conditions. The following are common reactions and the Properties, Uses, methods and safety information of the corresponding products:
1. Amidation reaction with N,N'-bis (mixed phenyl, tolyl and xylyl) guanidine hydrochloride to yield N,N'-bis (4-sulfophenyl)-4, 5-Dihydro-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylguanidine hydrochloride. This is an organic dye.
2. Complexation reaction with metal ions (such as Cu2, Fe3, etc.) to form corresponding complexes. These complexes are commonly used in dyes and indicators in biomedical and analytical chemistry.
3. React with amino compounds (such as ammonia) to generate the corresponding guanidinium products.
Nature:
Pyrazole red and its derivatives are red to dark red crystalline powder, soluble in water and alcohol, and have good red relative molecular mass.
Use:
Pyrazole red and its derivatives are mainly used in the dye industry as acid dyes, indicators and biological stains. It also has applications in the biomedical field, such as nuclear staining and protein detection.
Preparation Method:
The synthesis of pyrazole red is mainly through the reaction of benzoic acid and nitrous acid to generate 2-nitrobenzoic acid. Then, the coupling reaction of 2-nitrobenzoic acid with thaoxine (benzodiazepine) produces 4-nitro-4 '-aminobiphenyl. Finally, 4-nitro-4 '-aminobiphenyl reacts with sodium sulfide to reduce the nitro functional group of the mass center to obtain 4, 5-Dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid.
Safety Information:
Pyrazole red and its derivatives can generally be regarded as general harmful substances. Follow regular laboratory procedures and personal protection during use, and avoid contact with skin and eyes.
