4-AMINO-N-METHYLPHTHALIMIDE, also known as N-Methyl-4-aminophthalimide, is a chemical compound with the molecular formula C9H8N2O2. It is a white to off-white solid that is soluble in organic solvents. 4-AMINO-N-METHYLPHTHALIMIDE is often used as a reactant in the synthesis of pharmaceuticals and agrochemicals. It is also used as an intermediate in the production of dyes and pigments. 4-AMINO-N-METHYLPHTHALIMIDE has a variety of industrial applications and is important in the manufacturing of various products. However, it is important to handle this compound with care, as it may be harmful if ingested, inhaled, or absorbed through the skin.

Check Digit Verification of cas no

The CAS Registry Mumber 2257-85-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2257-85:
(6*2)+(5*2)+(4*5)+(3*7)+(2*8)+(1*5)=84
84 % 10 = 4
So 2257-85-4 is a valid CAS Registry Number.

On the photophysical properties of new luminol derivatives and their synthetic phthalimide precursors

Perez-Ruiz, Raul,Fichtler, Robert,Diaz Miara, Yrene,Nicoul, Matthieu,Schaniel, Dominik,Neumann, Helfried,Beller, Matthias,Blunk, Dirk,Griesbeck, Axel G.,Jacobi Von Wangelin, Axel

The photophysical properties of a series of structurally related 4-aminophthalimides and the corresponding 5-aminophthalic hydrazides (luminols) are reported. Absorption, steady-state, and time-resolved fluorescence spectra of luminols exhibited substitution, solvent, and pH dependence. Singlet lifetimes have been determined by time-resolved laser flash spectroscopy. UV spectra in gas phase and DMSO solution were calculated by TD-DFT which revealed the existence of two low-energy excited singlet states with strong pH-sensitivity.

Porcupine is an O-acyltransferase that regulates Wnt secretion. Inhibiting porcupine may block the Wnt pathway which is often dysregulated in various cancers. Consequently porcupine inhibitors are thought to be promising oncology therapeutics. A high throughput screen against porcupine revealed several potent hits that were confirmed to be Wnt pathway inhibitors in secondary assays. We developed a pharmacophore model and used the putative bioactive conformation of a xanthine inhibitor for scaffold hopping. The resulting maleimide scaffold was optimized to subnanomolar potency while retaining good physical druglike properties. A preclinical development candidate was selected for which extensive in vitro and in vivo profiling is reported.

A new efficient synthesis of substituted luminols using multicomponent reactions

Neumann, Helfried,Klaus, Stefan,Klawonn, Markus,Strübing, Dirk,Hübner, Sandra,G?rdes, Dirk,Von Wangelin, Axel Jacobi,Lalk, Michael,Beller, Matthias

, p. 431 - 438 (2007/10/03)

A new general synthesis of substituted luminols (5-amino-2,3- dihydrophthalazine-1,4-diones) is presented. Diversely substituted luminol derivatives can be synthesized in three steps. The products are of interest as new materials, which exhibit chemiluminescence.
