Trans-1,2-bis-(4-chlor-phenyl)-1,2-bis-dodecylmercapto-ethylen, also known as 4,4'-(1,2-ethenediyl)bis(N-dodecylbenzenesulfonamide), is a complex organic compound with the chemical formula C34H58Cl2N2O4S2. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. trans-1,2-Bis-(4-chlor-phenyl)-1,2-bis-dodecylmercapto-ethylen is characterized by its unique structure, featuring two 4-chlorophenyl groups connected by an ethylene bridge, with two dodecylmercapto groups attached to the ends. It is primarily used as a high-performance liquid chromatography (HPLC) stationary phase, particularly in the separation of chiral compounds. Due to its stability, selectivity, and high resolution capabilities, it is widely employed in the pharmaceutical and chemical industries for the analysis and purification of enantiomers.
The CAS Registry Mumber 5216-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5216-40: (6*5)+(5*2)+(4*1)+(3*6)+(2*4)+(1*0)=70 70 % 10 = 0 So 5216-40-0 is a valid CAS Registry Number.
