General Description
2-methyl-1,4-diaminobutane, also known as 1,4-butane diamine or putrescine, is an organic compound. Its chemical formula is C5H14N2. It is a diamine that plays a major role in the biosynthesis of various proteins. It is a colorless solid, although old or exposed samples can appear yellow. 2-methyl-1,4-diaminobutane gives off a strong odor and is produced in small amounts in the human body by the breakdown of amino acids. It's extensively used in the production of polymers, specifically in the manufacture of rubber, resins, and other polyamide based polymers. The compound is also used in the chemical industry as a precursor to various products, including pharmaceuticals. It can be hazardous if inhaled or contacted with skin and eyes, hence caution is required when handling it.
Check Digit Verification of cas no
The CAS Registry Mumber 15657-58-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,5 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15657-58:
(7*1)+(6*5)+(5*6)+(4*5)+(3*7)+(2*5)+(1*8)=126
126 % 10 = 6
So 15657-58-6 is a valid CAS Registry Number.

Synthesis of 2-Alkylputrescines from 3-Alkylpyrroles
Garrido, Daniel O. A.,Buldain, Graciela,Ojea, Maria I.,Frydman, Benjamin

Acylation of 2-(trichloroacetyl)pyrrole gave the 4-acyl derivatives (from 4-formyl to 4-hexanoyl) in good yields.Alkaline treatment gave corresponding 4-acyl-2-pyrrolecarboxylic acids, were decarboxylated to the 3-acylpyrroles by prior conversion to the 3-acyl-2,4,5-triiodopyrroles followed by hydrogenolysis.The 3-acylpyrroles were reduced by treatment with hydrazine in alkaline medium to the 3-alkylpyrroles.The latter were ring-opened by treatment with hydroxylamine in the presence of bicarbonate to give the dioximes of the corresponding 2-alkylsuccinaldehydes, which were then reduced to the 2-alkylpurescines (1,4-diaminobutanes).Ring-opening of 2,3-dimethylpyrrole followed by reduction of the dioxime gave 1,2-dimethylputrescine; the same sequence gave 1,3-dimethylputrescine from 2,4-dimethylpyrrole, while 3,4-dimethylpyrrole did not ring-open and gave the dioxime of 3,4-dimethylmaleimide.
