CAS 5402-20-0
:4-Pyridinesulfonic acid
Description:
4-Pyridinesulfonic acid, with the CAS number 5402-20-0, is an aromatic sulfonic acid characterized by the presence of a pyridine ring substituted with a sulfonic acid group at the fourth position. This compound is typically a white to light yellow crystalline solid that is soluble in water, reflecting its polar nature due to the sulfonic acid functional group. It exhibits acidic properties, making it useful in various chemical reactions and applications, including as a pH regulator and in the synthesis of other organic compounds. The presence of the pyridine ring contributes to its ability to participate in electrophilic substitution reactions. Additionally, 4-pyridinesulfonic acid can act as a ligand in coordination chemistry and is utilized in the preparation of dyes and pharmaceuticals. Its stability under standard conditions and reactivity with bases to form salts further enhance its utility in chemical synthesis and industrial applications.

CAS:<p>4-Pyridinesulphonic acid (4PS) is a functional group that has been shown to be able to replace chloride in organic synthesis. It can be introduced into organic compounds by oxidation of the 4-hydroxypyridine with phosphorus pentachloride or tetrazole, which leads to an introduction of a sulphonic acid group. This reaction can be carried out at room temperature and is bifunctional, meaning that it can produce both the 4PS and the product molecule.</p>Formula:C5H5NO3SPurity:Min. 95%Molecular weight:159.16 g/mol
