N,N'-Dicyclohexyl-N,N'-dimethyl-N''-phenyl-guanidine, also known as DCHMG, is a complex organic compound with the chemical formula C23H38N4. It is a derivative of guanidine, featuring two cyclohexyl groups, two methyl groups, and a phenyl group attached to the guanidine core. This chemical is primarily used as a catalyst in the production of polyurethane foams, where it promotes the reaction between isocyanates and polyols. DCHMG is known for its high activity and selectivity, which allows for the creation of flexible and rigid foams with desirable properties. It is also valued for its low volatility and minimal odor, which are beneficial in applications where these characteristics are important. The compound is typically synthesized through a multi-step process involving the reaction of phenylbiguanide with dimethyl sulfate and cyclohexylamine. Due to its specific applications and properties, DCHMG is an important chemical in the polyurethane industry.
The CAS Registry Mumber 4833-43-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 3 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4833-43: (6*4)+(5*8)+(4*3)+(3*3)+(2*4)+(1*3)=96 96 % 10 = 6 So 4833-43-6 is a valid CAS Registry Number.
