20637-04-1 Usage

General Description

Methyl 4-(4-chlorophenyl)butanoate is a chemical compound with the molecular formula C11H13ClO2. It is an ester, with a butanoate group attached to a methyl group and a 4-(4-chlorophenyl) moiety. This chemical is commonly used as a flavoring agent and fragrance ingredient in the food and cosmetic industries. It can also be used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Methyl 4-(4-chlorophenyl)butanoate is known for its sweet, fruity odor and is often used to impart a pineapple-like aroma to various products. It is important to handle this chemical with caution, as it may cause skin and eye irritation and should be stored and disposed of properly.

Check Digit Verification of cas no

The CAS Registry Mumber 20637-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20637-04:
(7*2)+(6*0)+(5*6)+(4*3)+(3*7)+(2*0)+(1*4)=81
81 % 10 = 1
So 20637-04-1 is a valid CAS Registry Number.

Copper-Catalyzed Conjugate Addition of Carbonyls as Carbanion Equivalent via Hydrazones

Luo, Siyi,Peng, Marie,Querard, Pierre,Li, Chen-Chen,Li, Chao-Jun

, p. 13111 - 13117 (2021/09/18)

Copper-catalyzed conjugate addition is a classic method for forming new carbon-carbon bonds. However, copper has never showed catalytic activity for umpolung carbanions in hydrazone chemistry. Herein, we report a facile conjugate addition of hydrazone catalyzed by readily available copper complexes at room temperature. The employment of mesitylcopper(I) and electron-rich phosphine bidentate ligand is a key factor affecting reactivity. The reaction allows various aromatic hydrazones to react with diverse conjugated compounds to produce 1,4-adducts in yields of about 20 to 99%.

Reductive C-C Coupling by Desulfurizing Gold-Catalyzed Photoreactions

Zhang, Lumin,Si, Xiaojia,Yang, Yangyang,Witzel, Sina,Sekine, Kohei,Rudolph, Matthias,Rominger, Frank,Hashmi, A. Stephen K.

, p. 6118 - 6123 (2019/07/03)

[Au2(μ-dppm)2]Cl2-mediated photocatalysis reactions are usually initiated by ultraviolet A (UVA) light; herein, an unreported system using blue light-emitting diodes (LEDs) as excitation light source was found. The red shift of the absorption wavelength originates from the combination of [Au2(μ-dppm)2]Cl2 and ligand (Ph3P or mercaptan). On the basis of this finding, a gold-catalyzed reductive desulfurizing C-C coupling of electrophilic radicals and styrenes mediated by blue LEDs is presented, a coupling which cannot be efficiently accessed by previously reported methods. This mild and highly efficient C-C bond formation strategy uses mercaptans both as electron-deficient alkyl radical precursor as well as the hydrogen source. Two examples of amino acids have also been modified by using this strategy. Moreover, this methodology could be applied in polymer synthesis. Gram-scale synthesis and mechanistic insights into this transformation are also presented.

Removal of human ether-à-go-go related gene (hERG) K+ channel affinity through rigidity: A case of clofilium analogues

Louvel, Julien,Carvalho, Jo?o F.S.,Yu, Zhiyi,Soethoudt, Marjolein,Lenselink, Eelke B.,Klaasse, Elisabeth,Brussee, Johannes,Ijzerman, Adriaan P.

supporting information, p. 9427 - 9440 (2014/01/06)

Cardiotoxicity is a side effect that plagues modern drug design and is very often due to the off-target blockade of the human ether-à-go-go related gene (hERG) potassium channel. To better understand the structural determinants of this blockade, we design
