98276-57-4 Usage

Uses

Used in Pharmaceutical Industry:
2,4-DIAMINOBENZALDEHYDE is used as a reagent for the synthesis of various pharmaceutical compounds. One of its applications is in the preparation of 6-(trifluoromethyl)-N-(4-oxothiazolidin-3-yl)quinazoline-2-carboxamide derivatives, which are considered potential DprE1 inhibitors. These inhibitors are significant in the development of new drugs targeting bacterial infections, particularly those caused by drug-resistant strains.

Check Digit Verification of cas no

The CAS Registry Mumber 98276-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,7 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98276-57:
(7*9)+(6*8)+(5*2)+(4*7)+(3*6)+(2*5)+(1*7)=184
184 % 10 = 4
So 98276-57-4 is a valid CAS Registry Number.

Versatile Barium and Calcium Imidazolium-Dicarboxylate Heterogeneous Catalysts in Quinoline Synthesis

Albert-Soriano, María,Trillo, Paz,Soler, Tatiana,Pastor, Isidro M.

supporting information, p. 6375 - 6381 (2017/12/01)

This article details the development of heterogeneous catalysts based on calcium and barium in combination with the organic linker 1,3-bis(carboxymethyl)imidazolium (bcmim). The linker and the materials from alkaline earth metals are easily prepared under very smooth conditions. The use of linkers with different counterions (Cl or Br) provided different materials. Calcium- and barium-based catalysts were successfully employed in the preparation of quinoline derivatives from ketones and 2-aminoarylaldehydes or 2-aminoarylketones. In general, barium-based catalysts provided better results than calcium, although the latter are an excellent complement for certain substrates. Thus, a notable feature of such catalysts is the possibility of accessing a variety of complementary heterogeneous catalytic systems, rendering the catalysis adaptive to the reactant.||||||.

Ni@Pd core-shell nanoparticles supported on a metal-organic framework as highly efficient catalysts for nitroarenes reduction

Jian, Siping,Li, Yingwei

, p. 91 - 97 (2016/01/12)

Ni@Pd core-shell nanoparticles with a mean particle size of 8-9 nm were prepared by solvothermal reduction of bivalent nickel and palladium in oleylamine and trioctylphosphine. Subsequently, the first-ever deposition of Ni@Pd core-shell nanoparticles having different compositions on a metal-organic framework (MIL-101) was accomplished by wet impregnation in n-hexane. The Ni@Pd/MIL-101 materials were characterized by powder X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and energy-dispersive X-ray spectroscopy and also investigated as catalysts for the hydrogenation of nitrobenzene under mild reaction conditions. At 30 °C and 0.1 MPa of H2 pressure, the Ni@Pd/MIL-101 gives a TOF as high as 375 h-1 for the hydrogenation of nitrobenzene and is applicable to a wide range of substituted nitroarenes. The exceptional performance of this catalyst is believed to result from the significant Ni-Pd interaction in the core-shell structure, together with promotion of the conversions of aromatics by uncoordinated Lewis acidic Cr sites on the MIL-101 support.

Plant antitumor agents. 25. Total synthesis and antileukemic activity of ring a substituted camptothecin analogues. Structure-activity correlations

Wani,Nicholas,Manikumar,Wall

, p. 1774 - 1779 (2007/10/02)

Nineteen racemic ring A substituted analogues of the antitumor agent 20(S)-camptothecin were prepared by total synthesis and evaluated for in vitro cytotoxic activity against KB cell culture and in vivo antileukemic activity against L1210. These compounds bore a wide variety of substitutents at C11 designed to confer upon the ring system a broad range of combinations of electronic, steric, and lipophilic effects. A few C10-substituted derivatives as well as C10,C11-disubstituted analogues prepared as part of a concurrent study have also been included for general comparison. With the notable exception of the cyano derivative, the 11-substituted compounds displayed only modest in vitro and in vivo activities, and there was a remarkable insensitivity toward the nature of the substituent. In contrast, the 9- and 10-substituted compounds exhibited a considerably higher level of dose potency and activity both in vitro and in vitro.
