6-(2,4-Dinitro-benzolazo)-3-methoxy-diphenylsulfid is a complex organic compound with the chemical formula C19H15N5O5S. It is characterized by a diphenylsulfide core, which consists of two phenyl rings connected by a sulfur atom. One of the phenyl rings is substituted with a methoxy group (-OCH3), while the other is attached to a 2,4-dinitro-benzolazo group. This group is a chromophore that gives the compound its color and is derived from the coupling of a 2,4-dinitrophenyl group with a benzolazo moiety. The compound is known for its potential applications in analytical chemistry, particularly as a reagent for the detection and quantification of certain metal ions due to its ability to form colored complexes with them. Its synthesis and use in colorimetric assays can provide valuable insights into the presence and concentration of specific metals in various samples.

1657-78-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1657-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1657-78:
(6*1)+(5*6)+(4*5)+(3*7)+(2*7)+(1*8)=99
99 % 10 = 9
So 1657-78-9 is a valid CAS Registry Number.
