Dibutyl mercaptal, also known as dibutyl sulfide, is an organic compound with the chemical formula C8H18S. It is a colorless liquid with a strong, unpleasant odor, and it is insoluble in water but soluble in organic solvents. Dibutyl mercaptal is primarily used as a synthetic intermediate in the production of various chemicals, such as rubber accelerators, pesticides, and pharmaceuticals. It is also employed as a solvent and a stabilizer in the manufacturing of certain polymers. Due to its strong odor, dibutyl mercaptal is sometimes used as an odorant in natural gas to help detect leaks. However, it is important to note that dibutyl mercaptal is toxic and can cause respiratory and skin irritation, so proper safety measures should be taken when handling this chemical.
The CAS Registry Mumber 5747-20-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 7 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5747-20: (6*5)+(5*7)+(4*4)+(3*7)+(2*2)+(1*0)=106 106 % 10 = 6 So 5747-20-6 is a valid CAS Registry Number.
