21354-40-5 Usage

General Description

2,2-dimethyl-N-(4-methylphenyl)propanamide, also known as DMPA, is a chemical compound used as an industrial chemical intermediate and as a building block in the production of various products. It is a white solid substance that is soluble in organic solvents and has a melting point of approximately 75-77°C. DMPA is commonly used in the production of pharmaceuticals for various medical applications, as well as in the synthesis of other organic compounds. It is important to handle DMPA with caution, as it can be harmful if swallowed or inhaled, and may cause skin and eye irritation upon contact. Additionally, it may have environmental and health hazards if not handled or disposed of properly.

Check Digit Verification of cas no

The CAS Registry Mumber 21354-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,5 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21354-40:
(7*2)+(6*1)+(5*3)+(4*5)+(3*4)+(2*4)+(1*0)=75
75 % 10 = 5
So 21354-40-5 is a valid CAS Registry Number.

supporting information, (2021/04/19)

An efficient and practical methodology for the synthesis of N-arylamides has been developed via copper-catalyzed amidation of diaryliodonium salts with nitriles. Various substituted aryl nitriles and aliphatic nitriles could be applied in the reaction, providing a series of N-arylated amides in moderate to good yields. This procedure provides an alternative route for the synthesis of various N-arylamides. A proposed mechanism based on control experiments is also presented.

Preparation method of N-aryl amide compound

-

Paragraph 0040-0045, (2020/07/13)

The invention discloses a preparation method of an N-aryl amide compound, which comprises the following steps: (1) putting diaryliodonium salt and Cu(OAc)2 into a Schlenk tube provided with a magneticstirring rod; (2) sequentially adding DCE, H2O and nitrile by using an injector, sealing the Schlenk tube, and stirring for reaction at 80 DEG C; (3) cooling the obtained solution to room temperature, and performing extraction with EtOAc; and combining organic layers, performing washing with saline water, and performing drying with anhydrous Na2SO4; and (4) removing volatile matters in vacuum, and purifying residues through column chromatography to obtain the N-aryl amide compound. Through a large number of experiments, a substrate with a simple structure is screened, the reaction conditionsare mild, the yield is high, the pollution is small, and the application prospect is wide.
