In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Rapid detection of copper ions of simulated Wilson′s disease urine based on surface-enhanced Raman spectroscopy, published in 2021, which mentions a compound: 4556-23-4, Name is Pyridine-4-thiol, Molecular C5H5NS, Recommanded Product: 4556-23-4.
Wilson′s disease (WD) is an autosomal recessive inherited disease. It is characterized by liver cirrhosis and brain degeneration caused by copper (Cu) metabolic disorder, which is one of the few neurogenetic diseases that can be treated, but improper treatment will cause disability or even death. This research constructed a method for detecting Cu2+ based on surface-enhanced Raman spectroscopy (SERS). The gold nanorods (AuNRs) substrates modified with 4-mercaptopyridine (Mpy) with uniform morphol. and dense hot spots were prepared Due to the existence of lone pairs of electrons in the nitrogen atom (N) on the pyridine ring, Cu2+ could coordinate with it to change the Raman spectrum of Mpy and realized the detection of Cu2+ with high sensitivity and selectivity. Under the condition of 25°C and reaction time of 2 min, the linear range of detection was 4.9×10-8-1×10-4 mol/L, with a detection limit of 49 nmol/L (S/N=3). This method was applied to the detection of Cu2+ in artificial urine, and the relative standard deviation (RSD) was less than 7.8%. The presented method here was simple, fast and accurate, and the detection process was nondestructive. And it had the potential to be applied to the early diagnosis and treatment of WD in the clinic.
There is still a lot of research devoted to this compound(SMILES：SC1=CC=NC=C1)Recommanded Product: 4556-23-4, and with the development of science, more effects of this compound(4556-23-4) can be discovered.
