Urea, N-(2-fluorophenyl)-N'-methyl-, also known as 1-(2-fluorophenyl)-3-methylurea or FMU, is an organic compound with the chemical formula C8H9FN2O. It is a derivative of urea, featuring a 2-fluorophenyl group attached to the nitrogen atom and a methyl group on the other nitrogen atom. Urea, N-(2-fluorophenyl)-N'-methyl- is primarily used as a fluorescent tracer in biological research, particularly in the study of nucleic acids and proteins. FMU exhibits strong fluorescence upon binding to these biomolecules, allowing for the visualization and analysis of their structure and function. Due to its unique properties, FMU has found applications in various fields, including molecular biology, biochemistry, and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 13140-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13140-07:
(7*1)+(6*3)+(5*1)+(4*4)+(3*0)+(2*0)+(1*7)=53
53 % 10 = 3
So 13140-07-3 is a valid CAS Registry Number.

Assignment of Isomeric Hydroxyhydantoins: Linked-scan, Tandem and High-resolutions Studies

Onisko, Bruce,Chang, Lydia,Lewis, Sydell

, p. 125 - 131 (2007/10/02)

The mass spectral fragmentation of hydroxyhydantoins was studied by a combination of high-resolution, linked-scan and collisionally activated decomposition (CAD) experiments.The endeavor resulted in the structural assignment of four pairs of synthetic hydroxyhydantoin isomers.A key feature in differentiating 1-methyl-3-aryl-5-hydroxy-2,4-imidazolidinediones from 1-aryl-3-methyl-5-hydroxy-2,4-imidazolidinediones is that under electron ionization (EI) conditions only the 1-methyl-3-aryl-5-hydroxy-2,4-imidazolidinediones yield the +* ion.The analogous +* ion (where Ar is the aryl group) was present in the EI spectra of both isomers and its origins are explained by the linked-scan and CAD experiments performed.
