Pyridine-3-sulfonyl chloride is a reagent used in the synthesis of pyrimidine derivatives with anti-proliferative activity against negative breast cancer cells.
Pyridine-3-sulfonyl chloride is a chemical compound that binds to the active site of cytochrome P450 enzymes. It can be used to study the effects of matrix effect on reaction solution. Pyridine-3-sulfonyl chloride has been shown to have an UV absorption spectrum with a maximum at 280 nm and a p450 activity that is proportional to the concentration of human serum. This compound has been shown to inhibit kinase domain in vitro assays, which may have clinical relevance in the treatment of obesity., 16133-25-8.
In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. 16133-25-8, formula is C5H4ClNO2S, Name is Pyridine-3-sulfonyl chloride. For this reason, pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene).

Dai, Yizhe;Wu, Gang research published 《 Solid-State 17O NMR Studies of Sulfonate Jump Dynamics in Crystalline Sulfonic Acids: Insights into the Hydrogen Bonding Effect》, the research content is summarized as follows. We report variable-temperature (VT) 17O solid-state NMR spectra for three crystalline sulfonic acids: L-cysteic acid monohydrate (CA), 3-pyridinesulfonic acid (PSA), and p-toluenesulfonic acid monohydrate (TSA). We were able to analyze the exptl. VT 17O NMR spectra to obtain the activation barriers for SO3– jumps in these systems. Using the d. functional-based tight-binding (DFTB) method, we performed potential energy surface scans for SO3– jumps in the crystal lattice of CA, PSA, and TSA, as well as for three related crystalline sulfonic acids (taurine, homotaurine, and 4-aminobutane-1-sulfonic acid) for which relevant 17O solid-state NMR data are available in the literature. The calculated activation barriers are in reasonable agreement with the exptl. values. On the basis of the DFTB results, we hypothesized that activation barriers for SO3– jumps in the crystal lattice depend largely on the hydrogen bonding energy difference between the ground state and the transition state.
