20803-96-7 Usage

General Description

2-(phenylsulfonyl)propanoic acid, also known as fenoprofen, is a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing the levels of prostaglandins, which are chemicals that cause pain, inflammation, and fever in the body. It is commonly used to treat pain and inflammation associated with conditions such as osteoarthritis and rheumatoid arthritis. Fenoprofen is also sometimes prescribed to relieve menstrual cramps and other types of mild to moderate pain. However, it carries a risk of stomach ulcers, bleeding, and kidney damage, and should be used with caution, especially in elderly patients.

Check Digit Verification of cas no

The CAS Registry Mumber 20803-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,0 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20803-96:
87 % 10 = 7
So 20803-96-7 is a valid CAS Registry Number.

Ni/Ir-Catalyzed Photoredox Decarboxylative Coupling of S-Substituted Thiolactic Acids with Heteroaryl Bromides: Short Synthesis of Sulfoxaflor and Its SF5 Analog

Kanishchev, Oleksandr S.,Dolbier, William R.

supporting information, p. 7677 - 7681 (2017/06/06)

Metallaphotoredox cross-coupling reactions have recently emerged as a powerful tool for the construction of C(sp2)?C(sp3) bonds between alkyl chains and aromatic systems, including electron-deficient heteroaryls, which are known to be challenging coupling partners. In this article, we disclose the Ni/Ir-catalyzed photoredox decarboxylative coupling of readily available S-substituted thiolactic acids with electron-deficient heteroaryl bromides, which resulted in the formation of simple but otherwise not easily accessible heteroarenes with alkylsulfide side chains. To demonstrate a practical use of this coupling reaction, we have shown its efficiency in the one-step synthesis of a key intermediate in the synthesis of the recently marketed insecticide Sulfoxaflor, and for the short synthesis of SF5-Sulfoxaflor.

Following the rules of a systematic QSAR study aimed at designing new, more potent sweeteners, the synthesis of 2-arylsulfonylisovaleric acids was carried out.
