Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, U.S. Gov’t, Non-P.H.S., Analytical Chemistry (Washington, DC, United States) called Surface-Enhanced Raman Spectroscopy-Scanning Electrochemical Microscopy: Observation of Real-Time Surface pH Perturbations, Author is Hatfield, Kendrich O.; Gole, Matthew T.; Schorr, Noah B.; Murphy, Catherine J.; Rodriguez-Lopez, Joaquin, which mentions a compound: 4556-23-4, SMILESS is SC1=CC=NC=C1, Molecular C5H5NS, Formula: C5H5NS.
Understanding and controlling chem. dynamics at electrode interfaces is key to electrochem. applications in sensing, electrocatalysis, and energy storage. Here, we introduce colocalized surface-enhanced Raman scattering-scanning electrochem. microscopy (SERS-SECM) as a multimodal tool able to simultaneously probe and affect electrochem. interfaces in real time. As a model system to demonstrate SERS-SECM, we used a self-assembled monolayer of 4-mercaptopyridine (4MPy), a pH sensitive Raman indicator, anchored to silver nanoparticles as a substrate. We modulated the local pH at the surface with chronoamperometry, inducing the hydrogen evolution reaction (HER) at the SECM tip and observed subsequent Raman peak height changes in the 4MPy. We then performed cyclic voltammetry of HER at the SECM tip while measuring SERS spectra every 200 ms to highlight the technique’s real-time capabilities. Our results show the capability to sensitively interrogate and trigger chem./electrochem. dynamic surface phenomena. We hope SERS-SECM will provide insight on the link between heterogeneous and homogeneous reactivity at electrochem. interfaces.
In addition to the literature in the link below, there is a lot of literature about this compound(Pyridine-4-thiol)Formula: C5H5NS, illustrating the importance and wide applicability of this compound(4556-23-4).
