1,3-bis-(2-ureido-ethyl)-benzene, also known as 1,3-Bis(2-ureidoethyl)benzene or BUEB, is an organic compound with the chemical formula C13H18N4O2. It is a white crystalline solid that is soluble in water and slightly soluble in organic solvents. BUEB is a crosslinking agent used in the synthesis of polyurethanes and other polymers, as it contains two ureido groups that can react with isocyanates to form urethane linkages. It is also used as a chelating agent for metal ions, particularly in the removal of heavy metals from wastewater. The compound is synthesized by reacting 1,3-phenylenediamine with ethylene carbonate in the presence of a catalyst. BUEB is considered a low-toxicity compound, but it should be handled with care due to its potential to cause skin and eye irritation.

3840-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3840-24-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.Calculate Digit Verification of CAS Registry Number 3840-24:
(6*3)+(5*8)+(4*4)+(3*0)+(2*2)+(1*4)=82
82 % 10 = 2
So 3840-24-2 is a valid CAS Registry Number.
