Description
7-(DIETHYLAMINO)COUMARIN-3-CARBOXYLIC is a fluorescent reagent known for its use in the circular dichroic exciton method for the derivatization of hydroxyl groups under mild conditions. It is characterized by its absorption at 406 nm, which is further in the red spectrum compared to other reagents such as naphthoylimidazole.
Uses
Used in Analytical Chemistry:
7-(DIETHYLAMINO)COUMARIN-3-CARBOXYLIC is used as a fluorescent derivatization reagent for the detection and analysis of hydroxyl groups in various compounds. Its application in the circular dichroic exciton method allows for the identification and quantification of hydroxyl-containing molecules under mild conditions, making it a valuable tool in analytical chemistry.
Used in Fluorescence Labeling:
7-(Diethylamino)-3-(imidazol-1-ylcarbonyl)-1-benzopyran-2-one, a derivative of 7-(DIETHYLAMINO)COUMARIN-3-CARBOXYLIC, is used as a reagent for labeling hydroxy compounds with fluorescent tags. This labeling process enhances the visibility and detection of these compounds, particularly in research and diagnostic applications where the study of hydroxy-containing molecules is crucial.
Check Digit Verification of cas no
The CAS Registry Mumber 261943-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,9,4 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 261943-47:
(8*2)+(7*6)+(6*1)+(5*9)+(4*4)+(3*3)+(2*4)+(1*7)=149
149 % 10 = 9
So 261943-47-9 is a valid CAS Registry Number.
