84984-48-5 Usage

General Description

2-acetyl-pent-4-enoic acid ethyl ester, also known as ethyl 2-acetyl-4-pentenoate, is a chemical compound with the molecular formula C9H14O3. It is an ester derived from acetylpent-4-enoic acid, and is commonly used in the flavor and fragrance industry due to its fruity, pineapple-like aroma. It can be found in various fruits and beverages, and is also used as a flavoring agent in food products. Additionally, it has been identified as a key component in the scent of certain flower species, and may also have potential applications in pharmaceutical or cosmetic formulations.

Check Digit Verification of cas no

The CAS Registry Mumber 84984-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,8 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84984-48:
(7*8)+(6*4)+(5*9)+(4*8)+(3*4)+(2*4)+(1*8)=185
185 % 10 = 5
So 84984-48-5 is a valid CAS Registry Number.

The immunoproteasome is a multicatalytic protease that is predominantly expressed in cells of hematopoietic origin. Its elevated expression has been associated with autoimmune diseases, various types of cancer, and inflammatory diseases. Selective inhibit

Electrochemical oxidative cyclization of olefinic carbonyls with diselenides

Guan, Zhipeng,Wang, Yunkun,Wang, Huamin,Huang, Yange,Wang, Siyuan,Tang, Hongding,Zhang, Heng,Lei, Aiwen

supporting information, p. 4976 - 4980 (2019/09/30)

The tandem cyclization of olefinic carbonyls with easily accessible diselenides facilitated by electrochemical oxidation has been successfully developed, which provides an environmentally friendly method for the construction of C-Se and C-O bonds simultaneously. A series of seleno dihydrofurans and seleno oxazolines, bearing fragile heterocycles, subtle C-I bonds and supernumerary vinyl groups, were forged using this elegant chelation strategy. Neither metal catalysts nor external chemical oxidants are required to promote this transformation.

A distinctive transformation based diversity oriented synthesis of small ring carbocycles and heterocycles from biocatalytically derived enantiopure α-substituted-β-hydroxyesters

Halder, Joydev,Das, Debabrata,Nanda, Samik

, p. 2549 - 2575 (2018/04/12)

A series of structurally novel small ring carbocyclic and heterocyclic molecules were accessed in an enantiopure fashion. The starting materials, α-substituted-β-hydroxyesters, were achieved through the biocatalytic dynamic kinetic resolution of parent β-
