Air & Water Reactions
Highly flammable. Slowly decomposes in air. Water soluble.
Reactivity Profile
N,N,N',N'-TETRAMETHYL-1,3-BUTANEDIAMINE may be sensitive to air and heat . Can burn in air to give toxic NOx gases . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Fire Hazard
N,N,N',N'-TETRAMETHYL-1,3-BUTANEDIAMINE is combustible.
Check Digit Verification of cas no
The CAS Registry Mumber 97-84-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97-84:
(4*9)+(3*7)+(2*8)+(1*4)=77
77 % 10 = 7
So 97-84-7 is a valid CAS Registry Number.
