350-90-3 Usage
Uses
Used in Pharmaceutical Industry:
ALPHA-FLUOROCINNAMIC ACID is used as a reagent for the biosynthesis of Coumarin (C755380), a pharmaceutic aid that serves as a flavoring agent. Coumarin is a naturally occurring compound found in various plants, such as tonka beans, lavender oil, woodruff, and sweet clover. It is valued for its aromatic properties and is utilized in the production of fragrances and flavorings.
Used in Chemical Synthesis:
ALPHA-FLUOROCINNAMIC ACID is used as a key intermediate in the synthesis of various chemical compounds, particularly those involving the formation of β-fluorostyrene through a decarboxylation reaction. This reaction is facilitated by the presence of copper, making it a valuable compound in the field of organic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 350-90-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 350-90:
(5*3)+(4*5)+(3*0)+(2*9)+(1*0)=53
53 % 10 = 3
So 350-90-3 is a valid CAS Registry Number.

Half-lives and fluorine atom shifts of stabilized 1-fluoro-l-lithioethenes bearing hydrogen, fluorine, phenyl, and/or dimethylphenylsilyl groups in the β-positions have been determined by a low-temperature 19F NMR spectroscopy. Some 1-fluoro-1-lithioethenes displayed an exceptionally low value of the trans-3JFF coupling constant. Stereoselectivity of carbenoid formation, as well as an effect of configuration on the stability is discussed.
