General Description
3'-Pyridylfluorone is a chemical compound with the molecular formula C13H7NO that is used as a fluorescent probe for detecting transition metal ions in biological and environmental samples. It is a yellowish-orange powder with a molecular weight of 197.20 g/mol and is soluble in organic solvents. 3'-Pyridylfluorone is known for its ability to form complexes with metal ions such as zinc, copper, and iron, making it useful for analytical and research applications. It has been studied for its potential use in medical diagnostics and environmental monitoring due to its high selectivity and sensitivity for certain metal ions. Additionally, 3'-Pyridylfluorone has been investigated for its potential use as a fluorescent label in bioimaging and molecular biology research.
Check Digit Verification of cas no
The CAS Registry Mumber 7638-44-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7638-44:
(6*7)+(5*6)+(4*3)+(3*8)+(2*4)+(1*4)=120
120 % 10 = 0
So 7638-44-0 is a valid CAS Registry Number.

Reliable synthesis of 9-aryl-substituted 2,6,7-trihydroxyxanthen-3-ones
Schrick, Petra,Geick, Klaus,Waldvogel, Siegfried R.
experimental part, p. 2211 - 2216 (2009/04/06)
2,6,7-Trihydroxyxanthen-3-ones are reliably prepared by a one-pot protocol using alkali peroxosulfates in the key step. NMR spectra in deuterated sodium hydroxide confirm the anticipated structures and allow the determination of the dye contents by an internal standard. Georg Thieme Verlag Stuttgart.
