(4-Methoxy-phenyl)-glyoxal-bis-(2,4-dinitro-phenylhydrazone) is a complex organic compound with the chemical formula C18H14N8O8. It is derived from glyoxal, a dialdehyde, and forms a bis-hydrazone with 2,4-dinitrophenylhydrazine, a reagent used for the detection and analysis of aldehydes and ketones. The compound features a 4-methoxy-phenyl group attached to the glyoxal backbone, which is then connected to two 2,4-dinitrophenylhydrazone moieties. This chemical is known for its yellow crystalline appearance and is used in various analytical applications, particularly in the detection of carbonyl compounds due to its distinct color change upon reaction. It is also of interest in the field of organic chemistry for its structural and functional properties.
The CAS Registry Mumber 13664-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,6 and 4 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 13664-91: (7*1)+(6*3)+(5*6)+(4*6)+(3*4)+(2*9)+(1*1)=110 110 % 10 = 0 So 13664-91-0 is a valid CAS Registry Number.
