Six positional isomers are possible for dinitrotoluene. The most common one is 2,4-dinitrotoluene. The nitration of toluene gives sequentially mononitrotoluene, DNT, and finally TNT. 2,4-DNT is the principal product from dinitration, the other main product being about 30% 1,3-DN2-T. The nitration of 4-nitrotoluene gives 2,4-DNT. [5]

2,4-Diaminotoluene is an aromatic organic compound with the formula C 6 H 3 (NH 2) 2 CH 3. It is one isomer of six with this formula. It is a white solid, although commercial samples are often yellow-tan.
Frederick Sanger. In 1945, Frederick Sanger described its use for determining the N-terminal amino acid in polypeptide chains, in particular insulin. [4] Sanger's initial results suggested that insulin was a smaller molecule than previously estimated (molecular weight 12,000), and that it consisted of four chains (two ending in glycine and two ending in phenylalanine), with the chains cross ...
Toluene diisocyanate (TDI) is an organic compound with the formula CH 3 C 6 H 3 (NCO) 2.Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.
4-Nitrotoluene or para-nitrotoluene is an organic compound with the formula CH 3 C 6 H 4 NO 2. It is a pale yellow solid. It is a pale yellow solid. It is one of three isomers of nitrotoluene .
2,4-Di-tert-butylphenol (2,4-DTBP) is a white solid with a phenolic odour. It is primarily used as a raw material for the production of several commercially important antioxidants and phenolic benzotriazole-type UV absorbers. It also finds use as a starting material in the synthesis of agrochemicals, fragrances and catalysts (i.e. Jacobsen's ...
