(E)-2,4-dinitro-phenylhydrazono-acetic acid is a chemical compound with the molecular formula C8H6N4O5. It is a derivative of acetic acid, where the carboxylic acid group is replaced by a phenylhydrazone moiety. The compound is characterized by the presence of two nitro groups (NO2) at the 2nd and 4th positions of the phenyl ring, which imparts a yellow color to the molecule. ((E)-2,4-dinitro-phenylhydrazono)-acetic acid is often used in organic synthesis and as a reagent in analytical chemistry, particularly for the detection and determination of aldehydes and ketones due to its ability to form colored complexes with these functional groups. The (E) configuration indicates the geometric isomerism around the double bond, which is important for its chemical properties and reactivity.

6155-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6155-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,5 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6155-31:
(6*6)+(5*1)+(4*5)+(3*5)+(2*3)+(1*1)=83
83 % 10 = 3
So 6155-31-3 is a valid CAS Registry Number.
