63546-89-4 Usage
General Description
2,3-Dihydro-2,3-bis(4-methylphenyl)-1,4-phthalazinedione, also known as DIBMP, is a chemical compound with a phthalazine backbone. It is a yellow crystalline powder that is insoluble in water but soluble in organic solvents. DIBMP is commonly used as a reducing agent in organic synthesis and as a dye intermediate in the production of various colorants and pigments. It is also used in the pharmaceutical industry for the synthesis of various pharmaceutical compounds. DIBMP is known to have low toxicity and is considered to be relatively safe to handle when used in accordance with proper safety precautions.
Check Digit Verification of cas no
The CAS Registry Mumber 63546-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63546-89:
(7*6)+(6*3)+(5*5)+(4*4)+(3*6)+(2*8)+(1*9)=144
144 % 10 = 4
So 63546-89-4 is a valid CAS Registry Number.

Electrochemical Conversion of Phthaldianilides to Phthalazin-1,4-diones by Dehydrogenative N?N Bond Formation
Kehl, Anton,Gieshoff, Tile,Schollmeyer, Dieter,Waldvogel, Siegfried R.
, p. 590 - 593 (2018)
The electrochemical synthesis of 6-membered rings via anodic dianilide N?N coupling is challenging due to concurring benzoxazole co-formation. The rigidity of the a phthalic acid backbone allows a novel access to phthalazin-1,4-diones by N?N bond formation using anodically generated amidyl radicals. Since conventional synthetic routes to phthalazin-1,4-diones require the use of toxic N,N′-diarylhydrazines and generate reagent waste, a safer and more sustainable approach is required. Easy accessible starting materials, a broad scope of applicable functional groups, promising yields, and a very simple set-up elevate this sustainable method.
