1,5-bis-(2-amino-ethyl)-2,4-dimethyl-benzene, also known as 2,4-dimethyl-1,5-bis(2-aminoethyl)benzene, is an organic compound with the molecular formula C12H20N2. It is a colorless to pale yellow crystalline solid that is soluble in water and various organic solvents. This chemical is primarily used as a monomer in the production of polyamides, specifically in the synthesis of nylon-66, a widely used thermoplastic polymer known for its strength, durability, and resistance to heat and wear. The compound is also used in the manufacturing of other polymers and resins, as well as in the production of certain dyes and pigments. Due to its reactive amino groups, it can form strong intermolecular hydrogen bonds, contributing to the properties of the polymers it helps to create.
The CAS Registry Mumber 1205-44-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 5 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1205-44: (6*1)+(5*2)+(4*0)+(3*5)+(2*4)+(1*4)=43 43 % 10 = 3 So 1205-44-3 is a valid CAS Registry Number.
