(4E)-5-(4-fluorophenyl)-4-[hydroxy(4-methylphenyl)methylidene]-1-(pyridin-3-ylmethyl)pyrrolidine-2,3-dione is a complex organic compound with a molecular formula of C25H22FNO3. It is characterized by a pyrrolidine-2,3-dione core, which is a four-membered ring with two carbonyl groups. The compound features a 4-fluorophenyl group attached to the 5-position of the pyrrolidine ring, a hydroxy(4-methylphenyl)methylidene group at the 4-position, and a pyridin-3-ylmethyl group at the 1-position. This molecule exhibits a trans (E) configuration, indicating the geometric arrangement of the double bond. It is a derivative of a pyrrolidine-2,3-dione scaffold, which is a common structural motif in various biologically active compounds and pharmaceuticals. The presence of fluorine, a methyl group, and a pyridine ring in (4E)-5-(4-fluorophenyl)-4-[hydroxy(4-methylphenyl)methylidene]-1-(pyridin-3-ylmethyl)pyrrolidine-2,3-dione suggests potential applications in medicinal chemistry, possibly as a precursor or intermediate in the synthesis of drugs targeting specific receptors or enzymes.

6652-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6652-52-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,5 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6652-52:
(6*6)+(5*6)+(4*5)+(3*2)+(2*5)+(1*2)=104
104 % 10 = 4
So 6652-52-4 is a valid CAS Registry Number.

Ionization Constants of 3-Substituted Propiolic Acids in Water

Laurence, Christian,Guilleme, Jean,Kirschleger, Bernard

, p. 1341 - 1343 (2007/10/02)

The pKa of ten 3-substituted propiolic acids XCCCO2H with X = OPh, Me, Ph, SiMe3, SPh, H, I, Cl, Br, and CO2Et have been measured at 25 deg C in water by a conductance method.The effect of substituents has been compared in the propiolic, acrylic, and benzoic series by means of linear free energy relationships.It is found that the Hammett and the DSP equations are less precisely obeyed in the propiolic series.Significant deviations occur for hydrogen and iodine which confirm the positive character of these groups when bound to an ethynyl group.
