136764-87-9 Usage

General Description

Methyl 2-methyl-2-(2-nitrophenyl)propionate is a chemical compound with the molecular formula C12H13NO4. It is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. METHYL 2-METHYL-2-(2-NITROPHENYL)PROPIONATE is known for its potential use as a flavoring agent due to its aromatic properties and is commonly used in the fragrance industry. The presence of a nitro group in its structure gives it exceptional reactivity and makes it a valuable building block in various chemical reactions. Additionally, it is also used in the production of perfumes, solvents, and other aroma chemicals due to its pleasant and lasting fragrance.

Check Digit Verification of cas no

The CAS Registry Mumber 136764-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,6 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136764-87:
(8*1)+(7*3)+(6*6)+(5*7)+(4*6)+(3*4)+(2*8)+(1*7)=159
159 % 10 = 9
So 136764-87-9 is a valid CAS Registry Number.

Synthesis of o-Aminophenols via a Formal Insertion Reaction of Arynes into Hydroxyindolinones

Chen, Zhilong,Wang, Qiu

, p. 6130 - 6133 (2015)

A novel approach toward the synthesis of sterically hindered o-aminophenols has been achieved by a formal aryne insertion into hydroxyindolinones. This transformation offers a rapid and efficient entry to diverse o-aminophenol scaffolds under mild transit

Design, synthesis and biological evaluation of novel human monoamine oxidase B inhibitors based on a fragment in an X-ray crystal structure

Cheng, Kai,Li, Shiyu,Lv, Xiao,Tian, Yongbin,Kong, Haiyan,Huang, Xufeng,Duan, Yajun,Han, Jihong,Xie, Zhouling,Liao, Chenzhong

supporting information, p. 1012 - 1018 (2019/02/24)

Herein we report our efforts of developing reversible selective hMAO-B inhibitors based on isatin, a fragment in an X-ray crystal structure. Five different scaffolds were designed and many compounds were synthesized. Among them, compound A3 demonstrated very high potency and isoform selectivity against hMAO-B, 11 and 13 times more potent (IC50 = 3 nM) and 23.64 and 6.8 times more selective than the marked drugs, selegiline and safinamide. However, the endeavors to modify the polar 3-one group of isatin, that is in a hydrophobic environment in the binding site of hMAO-B, to small nonpolar hydrophobic groups did not bring about improved hMAO-B inhibitors, which may challenge our understanding of molecular interactions and molecular recognition in biological systems.

Method for preparing and removing saccharide hydroxyl protecting group dimethyl phenylacetyl DMNA

-

Paragraph 0016; 0017; 0018; 0020, (2017/08/29)

The invention relates to a method for preparing and removing saccharide hydroxyl protecting group dimethyl phenylacetyl DMNA. The method comprises the following steps: (1) efficiently introducing saccharide hydroxyl protecting group dimethyl phenylacetyl into saccharide hydroxyl; and (2) efficiently removing a hydroxyl protecting group shown in the description. The method is environmentally friendly and has the advantages that the advantages that the preparation is simple, the introduction is efficient, the operation is easy, the removal is efficient, and the application range is wide; and furthermore, a protecting group has very good stereoselectivity when being used for protecting 2-hydroxyl of a glycosyl donor, so that the development and application of the protecting group are promoted.
