Toluene diisocyanate - Wikipedia
WEBToluene 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.
