6640-56-8 Usage

General Description

1-methyl-2-[(4-nitrophenyl)sulfanyl]benzene, also known as MNTB, is a chemical compound that consists of a benzene ring with a methyl group and a sulfanyl group attached to it, as well as a nitrophenyl group attached to the sulfur. It is a yellow solid with a molecular formula of C13H11NO2S and a molecular weight of 237.30 g/mol. MNTB is known for its use in organic synthesis and pharmaceutical research, particularly in the development of anti-cancer and anti-inflammatory drugs. It is also used as a precursor in the production of various compounds and as a reagent in chemical reactions. MNTB should be handled and stored carefully due to its potential health hazards, including irritant and toxic effects.

Check Digit Verification of cas no

The CAS Registry Mumber 6640-56-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,4 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6640-56:
(6*6)+(5*6)+(4*4)+(3*0)+(2*5)+(1*6)=98
98 % 10 = 8
So 6640-56-8 is a valid CAS Registry Number.

Cerium catalyst promoted C-S cross-coupling: Synthesis of thioethers, dapsone and RN-18 precursors

Tavares Junior, José M. Da C.,Da Silva, Caren D. G.,Dos Santos, Beatriz F.,Souza, Nicole S.,De Oliveira, Aline R.,Kupfer, Vicente L.,Rinaldi, Andrelson W.,Domingues, Nelson L. C.

supporting information, p. 10103 - 10108 (2019/12/23)

In this work, we present a novel, efficient and green methodology for the synthesis of thioethers by the C-S cross-coupling reaction with the assistance of [Ce(l-Pro)2]2Ox as a heterogeneous catalyst in good to excellent yields. A scale-up of the protocol was explored using an unpublished methodology for the synthesis of a dapsone-precursor, which proved to be very effective over a short time. The catalyst [Ce(l-Pro)2]2Ox was recovered and it was shown to be effective for five more reaction cycles.

Copper-catalyzed Ullmann coupling under ligand- and additive-free conditions. Part 2: S-Arylation of thiols with aryl iodides

Buranaprasertsuk, Pongchart,Chang, Joyce Wei Wei,Chavasiri, Warinthorn,Chan, Philip Wai Hong

, p. 2023 - 2025 (2008/09/19)

S-Arylation of a wide variety of substituted aryl and aliphatic thiols with aryl halides catalyzed by copper iodide under mild ligand- and additive-free conditions (nBu4NBr, PhMe, NaOH, reflux, 22 h) is accomplished in good to excellent product yields (up to 96%).
