S-methyl-1,5-di(phenyl)thiocarbazone, also known as SMDC, is an organic compound with the chemical formula C14H14N4S. It is a derivative of the thiocarbazone family, characterized by its sulfur-containing structure. SMDC is a white crystalline solid that is soluble in organic solvents such as ethanol and acetone. It is primarily used as a reagent in analytical chemistry for the detection and determination of certain metal ions, particularly copper, silver, and gold. The compound forms colored complexes with these metals, which can be analyzed spectrophotometrically. SMDC is also of interest in the field of coordination chemistry due to its ability to bind to metal ions, making it a potential candidate for applications in metal extraction and sensing.
The CAS Registry Mumber 6846-17-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,4 and 6 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6846-17: (6*6)+(5*8)+(4*4)+(3*6)+(2*1)+(1*7)=119 119 % 10 = 9 So 6846-17-9 is a valid CAS Registry Number.
