1239-94-7 Usage
General Description
DANSYL-L-PROLINE is a chemical compound composed of the amino acid L-proline and the dansyl group, a fluorescent dye often used in protein and peptide labeling. It is commonly used as a fluorescent tag in biochemical and analytical applications, particularly in the study of protein folding and dynamics. The dansyl group emits strong fluorescence when exposed to ultraviolet light, making it a valuable tool for tracing and detecting biomolecules in a variety of experimental techniques, including fluorescence microscopy and flow cytometry. DANSYL-L-PROLINE is also utilized in the development of fluorescent sensors and probes for detecting and quantifying biological processes and interactions.
Check Digit Verification of cas no
The CAS Registry Mumber 1239-94-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1239-94:
(6*1)+(5*2)+(4*3)+(3*9)+(2*9)+(1*4)=77
77 % 10 = 7
So 1239-94-7 is a valid CAS Registry Number.

experimental part, p. 3793 - 3798 (2012/08/28)
Plipastatin A1 and fengycin IX were experimentally proven to be identical compounds, while these had been considered as diastereomers due to the permutation of the enantiomeric pair of Tyr in most papers. The 1H NMR spectrum changed to become quite similar to that of plipastatin A1, when the sample which provided resembled spectrum of fengycin IX was treated with KOAc followed by LH-20 gel filtration. Our structural investigations disclosed that the structures of these molecules should be settled into that of plipastatin A1 by Umezawa (l-Tyr4 and d-Tyr10).
