Chemical Properties

4,4'-METHYLENEBIS(2,6-DIISOPROPYLANILINE) is solidified melt

Uses

4,4'-METHYLENEBIS(2,6-DIISOPROPYLANILINE) is an excellent chain extender for elastomeric polyurethanes (PU) especially useful in systems cured at room temperature. It is also a curing agent for epoxides (EP) and an intermediate for organic syntheses.

Flammability and Explosibility

Nonflammable

Check Digit Verification of cas no

The CAS Registry Mumber 19900-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,0 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19900-69:
(7*1)+(6*9)+(5*9)+(4*0)+(3*0)+(2*6)+(1*9)=127
127 % 10 = 7
So 19900-69-7 is a valid CAS Registry Number.

Highly regioselective para-methylthiolation/bridging methylenation of arylamines promoted by NH4I

Xu, Yinfeng,Cong, Tiantian,Liu, Ping,Sun, Peipei

supporting information, p. 9742 - 9745 (2015/10/05)

Aryl methyl thioethers and methylene-bridged arylamines were synthesized via highly regioselective para-methylthiolation/bridging methylenation of arylamines using DMSO as the methylthio or methylene source in the presence of NH4I under metal-free conditions. For the substrates with both electron-donating and electron-withdrawing substituents, the reaction proceeded smoothly and gave moderate to good yields.
