Thiourea, N-methyl-N'-(1-methylethyl)-, also known as N,N'-dimethylthiourea or DMTU, is an organic compound with the chemical formula C4H10N2S. It is a colorless, crystalline solid that is soluble in water and various organic solvents. DMTU is primarily used as a corrosion inhibitor in metalworking fluids, as it forms a protective film on metal surfaces, preventing rust and corrosion. Additionally, it has applications in the rubber and plastics industries as a vulcanization accelerator and a flame retardant. DMTU is also used in the pharmaceutical industry as an intermediate for the synthesis of various drugs. Due to its potential health and environmental risks, proper handling and disposal procedures should be followed when working with this chemical.
The CAS Registry Mumber 4041-94-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,4 and 1 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4041-94: (6*4)+(5*0)+(4*4)+(3*1)+(2*9)+(1*4)=65 65 % 10 = 5 So 4041-94-5 is a valid CAS Registry Number.
