4450-68-4 Usage

General Description

The chemical compound 1-methyl-4-[(4-nitrophenyl)methoxysulfonyl]benzene, also known as NMBS, is an organic compound with the molecular formula C15H13NO5S. It is a sulfonamide derivative with a nitrophenyl group attached to a benzene ring, and a methyl group attached to the nitrogen atom. NMBS is a potentially hazardous chemical and should be handled with care. It is used in various research applications, including as a starting material in the synthesis of other organic compounds. NMBS has also been studied for its potential biological activity and may have applications in the development of pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 4450-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4450-68:
(6*4)+(5*4)+(4*5)+(3*0)+(2*6)+(1*8)=84
84 % 10 = 4
So 4450-68-4 is a valid CAS Registry Number.

Ionic liquid brush as an efficient and reusable heterogeneous catalytic assembly for the tosylation of phenols and alcohols in neat water

Feng, Simin,Li, Jing,Wei, Junfa

supporting information, p. 4743 - 4746 (2017/07/12)

A very efficient and reusable heterogeneous ionic liquid brush assembly was developed. The catalyst exhibits high catalytic activity for the tosylation of phenols and alcohols in neat water. Moreover, the catalyst shows outstanding stability and reusability, and it can be simply and effectively recovered and reused five times without noticeable loss of catalytic activity.

A dicationic, podand-like, ionic liquid water system accelerated copper-catalyzed azide-alkyne click reaction

Javaherian, Mohammad,Kazemi, Foad,Ghaemi, Masoumeh

, p. 1643 - 1647 (2015/01/09)

In this work, an effective, task specific, dicationic, podand-like ionic liquid was synthesized and applied to improve the capability features of click reaction. Moreover, to broaden the scope and decreasing the serious limitations of preparation methods of organic azides, a simple green procedure for the preparation of alkyl azides, the fundamental starting materials in click reactions, from alcohols under solvent-free conditions and microwave irradiation has been reported, for the first time.

Chemoselective and scalable preparation of alkyl tosylates under solvent-free conditions

Kazemi, Foad,Massah, Ahmad R.,Javaherian, Mohammad

, p. 5083 - 5087 (2008/02/01)

The improved method for the efficient tosylation of alcohols has been reported using two procedures (A and B). Procedure A: methanol, ethanol, benzyl alcohols, and valuable ethylene glycols can be converted into their corresponding alkyl tosylates in very fast, simple, and efficient grinding method using potassium carbonate as solid base. Other primary and secondary alcohols need to add potassium hydroxide to reaction mixture (procedure B). High selectivity of tosylation was observed for these two procedures. Scale up ability was found in this method even in 100 mmol of substrate. The present method is the example of solid-state tosylation using tosyl chloride, and is a green chemical process due to solvent-free conditions.
