42019-78-3 Usage

Chemical Properties

light grey to beige-brown powder

Uses

Different sources of media describe the Uses of 42019-78-3 differently. You can refer to the following data:
1. The Impurity of Fenofibric acid (42017-89-0), the active metabolite of fenofibrate which increases Apolipoprotein A-I–Mediated High-Density Lipoprotein Biogenesis by enhancing transcription of ATP-Binding cassette transporter A1 gene in a liver X receptor
2. 4-Chloro-4’-hydroxybenzophenone (Fenofibrate EP Impurity A; Fenofibrate USP Related Compound A) the impurity of Fenofibric acid (42017-89-0), the active metabolite of fenofibrate which increases Apolipoprotein A-I–Mediated High-Density Lipoprotein Biogenesis by enhancing transcription of ATP-Binding cassette transporter A1 gene in a liver X receptor–dependent manner.

Preparation

Preparation by Fries rearrangement of phenyl p-chloro-benzoate, ? in the presence of aluminium chloride, without solvent, at 160° for 5 min, between 120° and 160° (good yield) or at 130° for 1 h, then at 160° for 1 h (10%) or in refluxing chlorobenzene for 10 h (52%); ? in the presence of trifluoromethanesulfonic acid at 45–55° (94%).

Check Digit Verification of cas no

The CAS Registry Mumber 42019-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,1 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42019-78:
(7*4)+(6*2)+(5*0)+(4*1)+(3*9)+(2*7)+(1*8)=93
93 % 10 = 3
So 42019-78-3 is a valid CAS Registry Number.

Metal-free C-C bond formation: Via coupling of nitrile aimines and boronic acids

Livingstone, Keith,Bertrand, Sophie,Mowat, Jenna,Jamieson, Craig

, p. 10412 - 10416 (2019)

The challenges of developing sustainable methods of carbon-carbon bond formation remains a topic of considerable importance in synthetic chemistry. Capitalizing on the highly reactive nature of the nitrile imine 1,3-dipole, we have developed a novel metal-free coupling of this species with aryl boronic acids. Photochemical generation of a nitrile imine intermediate and trapping with a palette of boronic acids enabled rapid and facile access to a broad library of more than 25 hydrazone derivatives in up to 92% yield, forming a carbon-carbon bond in a metal free fashion. This represents the first reported example of direct reaction between boronic acids and a 1,3-dipole.

A sodium trifluoromethanesulfinate-mediated photocatalytic strategy for aerobic oxidation of alcohols

Zhu, Xianjin,Liu, Can,Liu, Yong,Yang, Haijun,Fu, Hua

supporting information, p. 12443 - 12446 (2020/10/30)

A sodium trifluoromethanesulfinate-mediated photocatalytic strategy for the aerobic oxidation of alcohols has been developed for the first time, and the photoredox aerobic oxidation of secondary and primary alcohols provided the corresponding ketones and carboxylic acids, respectively, in high to excellent yields.
