dinitrobenzene मीनिंग इन हिंदी

उदाहरण वाक्य

1. 1, 3-Dinitrobenzene is accessible by nitration of nitrobenzene.
2. Reduction of 1, 3-dinitrobenzene with sodium sulfide in aqueous solution leads to 3-nitroaniline.
3. Without these groups it is not possible to form the methylene compound which reacts with dinitrobenzene but triazolo compounds may react.
4. The 2-, 4-, and 6-positions on the pyrimidine ring are electron deficient analogous to those in pyridine and nitro-and dinitrobenzene.
5. Most mammalian isoenzymes have affinity for the substrate 1-chloro-2, 4-dinitrobenzene, and spectrophotometric assays utilising this substrate are commonly used to report GST activity.
6. 2, 4-Dinitroaniline can be prepared by reaction of 1-chloro-2, 4-dinitrobenzene with ammonia or by acid hydrolysis of 2, 4-dinitroacetanilide.
7. Two of the more common reagents are "'Sanger's reagent "'( 1-fluoro-2, 4-dinitrobenzene ) and dansyl derivatives such as dansyl chloride.
8. In vivo experiment of DNBS ( 2, 4-dinitrobenzene sulfonic acid ) induced rat colitis, a frequently used animal model for inflammatory bowel disease, showed comparable efficacy and greater potency than sulfasalazine.
9. It is a two-component reagent, with the first component composed of 1, 3-dinitrobenzene ( 1 % w / v ) in methanol and the second component composed of 15 % potassium hydroxide in water.
10. Sanger used a chemical reagent 1-fluoro-2, 4-dinitrobenzene ( now, also known as Sanger's reagent, fluorodinitrobenzene, FDNB or DNFB ), sourced from poisonous gas research by Bernhard Charles Saunders at the Chemistry Department at Cambridge University.
