Nitro

4-Nitrocatechol is a reactive chemical that has been used as an analytical reagent for the detection of nitrite ions. It reacts with nitrite ion to form stable complexes, which can be detected by titration calorimetry. 4-Nitrocatechol has also been used as a model for study of reaction mechanisms and coordination geometry. The reaction mechanism of 4-nitrocatechol is thought to involve formation of a dinucleotide phosphate intermediate and subsequent attack by the nitrite ion to produce an unstable intermediate that decomposes to form stable complexes with the nitrite ion.

1-(3-Chlorophenyl)-2-nitroethene is a reagent that is used as an intermediate in the production of fine chemicals, research chemicals, and speciality chemicals. It has been shown to provide a useful scaffold for the synthesis of complex compounds and is also a versatile building block that can be used in a variety of reactions. 1-(3-Chlorophenyl)-2-nitroethene is not intended for use as a drug or food additive.

3-Hydroxy-2-nitrobenzoic acid is a metabolite of 3-hydroxyanthranilic acid, which is an intermediate in the biosynthesis of amino acids. It can be found in animals and plants. 3-Hydroxy-2-nitrobenzoic acid has two isomers: 3,5-dihydroxybenzoic acid and 3,4,5-trihydroxybenzoic acid. The former is more abundant than the latter. In animal tissues, 3-hydroxybenzoic acid can be found as a diacid or as a salt with sodium or potassium. It reacts with various compounds to form oxidation products that have been shown to have sequences that are different from those of their precursors. These oxidation products are analyzed for the presence of their carboxylate group to identify the original compound. This carboxylate group can then be used as a ligand in matrix assisted laser desorption

4-tert-Butyl-2,6-dinitrophenol is a yellowish solid that is soluble in organic solvents. It is used as an intermediate for the synthesis of dyes, pesticides and pharmaceuticals. 4-tert-Butyl-2,6-dinitrophenol has been shown to cause respiratory tract irritation and narcosis in animals. The toxic effects of 4-tert-Butyl-2,6-dinitrophenol are due to its high electrophilicity and nitro group (NO) which causes oxidative stress. The logistic regression analysis showed that the population growth of ciliates was negatively affected by the presence of halogens in the water.

2,4-Dimethyl-3,5-dinitroaniline is a high quality chemical that is used as an intermediate in the synthesis of other compounds. It has been shown to be a useful building block for the synthesis of complex compounds. 2,4-Dimethyl-3,5-dinitroaniline is also a versatile building block and can be used in reactions involving nucleophilic substitution with electron transfer or nucleophilic addition. It has also been shown to be a useful scaffold for a variety of reactions including Friedel-Crafts alkylation and acylation. 2,4-Dimethyl-3,5-dinitroaniline is not available for sale to consumers or retailers.

4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals.

Methyl 3,5-dinitro-4-hydroxybenzoate is a reactive compound that can be used to glycosylates alcohols. It is a good choice for the glycosylation of complex oligosaccharides due to its high yields and stereoselectivity. Methyl 3,5-dinitro-4-hydroxybenzoate is an efficient method for the synthesis of oligosaccharides. Reaction with methanol and glycosyl acceptor yields a disaccharide in which the two sugars are linked by an alpha-(1,2) glycosidic bond. The nucleophilic nature of methyl 3,5-dinitro-4-hydroxybenzoate allows it to act as a nucleophile in the reaction with the glycosyl acceptor.

3-Methoxy-4-nitrobenzoic acid is a potent and selective inhibitor of aromatase that can be used for the treatment of breast cancer. 3-Methoxy-4-nitrobenzoic acid inhibits the activity of serine proteases, which are enzymes important in protein degradation and cellular signaling. This drug has been shown to inhibit the activity of many other types of kinases, and this makes it a good candidate for use as an anti-cancer agent. 3-Methoxy-4-nitrobenzoic acid also has been shown to inhibit the formation and development of brain tumors when administered via whole body or brain uptake techniques. In addition to inhibiting tumor growth, this drug can prevent metastasis by preventing circulating tumor cells from entering new tissues. The inhibition of estrogen synthesis by 3methoxy-4 nitrobenzoic acid leads to breast cancer cell death in vitro and in vivo.
