:PYRIDINE-3,5-DISULFONIC ACID
Description:
Pyridine-3,5-disulfonic acid is an aromatic sulfonic acid characterized by the presence of a pyridine ring substituted with two sulfonic acid groups at the 3 and 5 positions. This compound is typically a white to light yellow crystalline solid that is soluble in water due to the polar nature of the sulfonic acid groups. It exhibits strong acidic properties, making it useful in various chemical reactions and applications, including as a reagent in organic synthesis and as a pH indicator. The presence of the pyridine ring contributes to its ability to participate in coordination chemistry, potentially forming complexes with metal ions. Pyridine-3,5-disulfonic acid is also known for its role in biological systems, where it may act as a buffer or in the modification of biomolecules. Safety data indicates that, like many sulfonic acids, it should be handled with care, as it can be corrosive and may cause irritation upon contact with skin or eyes.
