(3-hydroxy-2-oxo-2,3-dihydro-indol-3-yl)-phosphonic acid diisopropyl ester is a complex organic compound with the molecular formula C13H18NO5P. It is a derivative of indole, a heterocyclic aromatic organic compound, and features a phosphonic acid group, which is a key component in many biologically active molecules. (3-hydroxy-2-oxo-2,3-dihydro-indol-3-yl)-phosphonic acid diisopropyl ester is characterized by a hydroxyl group at the 3-position and a carbonyl group at the 2-position of the indole ring, with the phosphonic acid moiety attached to the nitrogen atom. The diisopropyl ester group indicates that two isopropyl (C3H7) groups are esterified to the phosphonic acid, which can influence the compound's solubility and reactivity. This chemical structure suggests potential applications in medicinal chemistry, particularly in the development of drugs targeting enzymes or receptors that interact with phosphonic acid-containing molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 5044-63-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5044-63:
(6*5)+(5*0)+(4*4)+(3*4)+(2*6)+(1*3)=73
73 % 10 = 3
So 5044-63-3 is a valid CAS Registry Number.

ORGANOPHOSPHORUS CHEMISTRY, 27. THE REACTION OF ISATIN, 5-METHYLISATIN AND THEIR MONOXIMES WITH ALKYL PHOSPHITES, TRIPHENYLPHOSPHINE AND PHOSPHORUS YLIDES

Mahran, M. R. H.,Khidre, M. D.,Abdou, W. M.

, p. 17 - 28 (2007/10/02)

5-Methylisatin (1b) reacts with TAP (4a-c) and/or DAP (3a-c) to give the respective dialkyl α-hydroxyphosphonates (8a-c).Isatin-monoxime (5a) and 5-methyl isatin-monoxime (5b) react with alkyl phosphites to give dialkyl 2-oxo-indolyl phosphonates (8a-c, 12a-f, 15a-c) as major products.The carbonyl-group at position - 3 in 1b is deoxygenated by triphenylphosphine to give a new phosphorus ylide (17) and by methylenetriphenylphosphoranes (Wittig-reagents, 7a-c) to afford the respective 3-substituted methylenes (19a-c) in good yields.Possible reaction mechanisms were considered and structural assignments were based upon analytical, chemical and spectroscopic (IR, 1H NMR, 31P NMR and MS) results. Key words: Isatins, isatinmonoximes, phosphorylation, triphenylphsophine, Wittig-reaction.
