o-Nitrophenol (2-nitrophenol; OH and NO 2 groups are neighboring, a yellow solid. m-Nitrophenol (3-nitrophenol, CAS number: 554-84-7), a yellow solid (m.p. 97 °C) and precursor to the drug mesalazine (5-aminosalicylic acid). It can be prepared by nitration of aniline followed by replacement of the amino group via its diazonium derivative. [2]
4-Nitrophenol is a product of the enzymatic cleavage of several synthetic substrates such as 4-nitrophenyl phosphate (used as a substrate for alkaline phosphatase), 4-nitrophenyl acetate (for carbonic anhydrase), 4-nitrophenyl-β-D-glucopyranoside and other sugar derivatives which are used to assay various glycosidase enzymes.
The route name is a contraction of its earlier name of the Alexandria to Ashland Highway, which referenced two cities connected by the highway: Alexandria in Northern Kentucky and (via I-64) Ashland in Eastern Kentucky. The route is officially known as the John Y. Brown Jr. AA Highway, named for politician and entrepreneur. [2]
[4] Spy dust was detected in the Soviet Union in 1970s in tiny quantities. In 1984, KGB officer Sergei Votontsov (Code name GT/COWL) provided a sample of the substance. [4] Soviet defector Vitaly Yurchenko confirmed the chemical. [4] [6] In the summer of 1985 the powder began to appear in Moscow in much larger quantities.
When heating 2,3,4-pentanetrione with oxygen, the oxidation products are diacetyl, acetic acid, water and carbon dioxide. [9] Alkalis convert it into acetic acid and formaldehyde. [8] 2,3,4-Pentanetrione does a condensation reaction with o-phenylenediamine to yield methyl-quinoxaline-2-methylketone, a heterocyclic dicycle. In this the carbon ...
INT (iodonitrotetrazolium or 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyl-2H-tetrazolium) is a commonly used tetrazolium salt (usually prepared with chloride ions), similar to tetrazolium chloride that on reduction produces a red formazan dye that can be used for quantitative redox assays. It is also toxic to prokaryotes.
