Tris(methoxymethyl)urea, also known as TMU, is a chemical compound with the formula C6H15N3O3. It is a colorless, crystalline solid that is soluble in water and various organic solvents. TMU is primarily used as a crosslinking agent in the production of polyurethane foams, providing improved mechanical properties and dimensional stability. It is also employed as a blowing agent in the foam industry, generating gas to create foam structures. Additionally, TMU has applications in the synthesis of other chemicals and as a stabilizer in various industrial processes. Due to its potential health and environmental concerns, proper handling and disposal protocols are essential when working with tris(methoxymethyl)urea.

Check Digit Verification of cas no

The CAS Registry Mumber 13822-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,2 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13822-64:
(7*1)+(6*3)+(5*8)+(4*2)+(3*2)+(2*6)+(1*4)=95
95 % 10 = 5
So 13822-64-5 is a valid CAS Registry Number.

The Formation Pathway of 3,5-Bis(methoxymethyl)perhydro-1,3,5-oxadiazin-4-one

Shiba, Ryuichi,Takahashi, Miyuki,Ebisuno, Toichi,Takimoto, Michiaki

, p. 1930 - 1933 (1989)

The investigation of the reactions of urea and its methyl derivatives with formaldehyde elucidated the formation pathway of 3,5-bis(methoxymethyl)perhydro-1,3,5-oxadiazin-4-one. 1) The addition of formaldehyde to urea became increasingly difficult according to the increase of the number of added formaldehyde molecules, probably because of the steric hindrance of the hydroxymethyl groups. 2) 3,5-Bis(methoxymethyl)perhydro-1,3,5-oxadiazin-4-one was concluded to be derived from urea via tris(hydroxymethyl)urea and 3-(hydroxymethyl)perhydro-1,3,5-oxadiazin-4-one but not via tetrakis(hydroxymethyl)urea or perhydro-1,3,5-oxadiazin-4-one.
