2,4',4''-methanetriyl-tri-aniline, also known as tris(4-aminophenyl)methane or TAPM, is an organic compound with the chemical formula C21H24N3. It is a white crystalline solid that is soluble in organic solvents and has a melting point of approximately 150°C. 2,4',4''-methanetriyl-tri-aniline is a triazine derivative, characterized by a central methane molecule connected to three aniline groups. TAPM is primarily used as a monomer in the synthesis of various polymers, such as polyamides and polyimides, due to its high thermal stability and excellent mechanical properties. It is also employed as a curing agent for epoxy resins and as a precursor in the production of dyes and pigments. The compound is synthesized through the reaction of formaldehyde with aniline, and its structure and properties make it a valuable building block in the chemical industry for creating high-performance materials.

Check Digit Verification of cas no

The CAS Registry Mumber 641-29-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 641-29:
(5*6)+(4*4)+(3*1)+(2*2)+(1*9)=62
62 % 10 = 2
So 641-29-2 is a valid CAS Registry Number.
