Introduction of 2-Mercaptopyridine (C₅H₅NS) is an organosulfur compound with a pyridine ring and a thiol (-SH) group at the 2-position. A yellow crystalline solid with a sulfurous odor, it is soluble in organic solvents but poorly in water. Its weakly acidic thiol (pKa ~4.5–5) enables metal coordination, forming stable complexes with transition metals (e.g., Cu, Ni), making it valuable in catalysis and material science. Used as a ligand, synthetic intermediate in pharmaceuticals, and biochemical protein modifier. Toxic and irritant, it requires careful handling (gloves, ventilation). Distinct from 4-mercaptopyridine and its sodium salt (enhanced solubility). Avoid confusion with antifungal 2-mercaptopyridine N-oxide.
Application of Here's a detailed overview of 2-Mercaptopyridine:
Chemical Classification:
Organosulfur compound with a pyridine ring and a thiol (-SH) group at the 2-position.
Chemical Formula: C5H5NSC5H5NS.
CAS Number: 2637-34-5.
Other Names: 2-Pyridinethiol, 2-Thiopyridine.
Key Properties:
1. Physical State:
Yellow to off-white crystalline solid.
Distinctive sulfur-like odor (common for thiols).
2. Solubility:
Soluble in organic solvents (ethanol, DMSO, chloroform).
Poor solubility in water.
3. Acidity:
Weakly acidic (pKa ~4.5–5.0 for the thiol group).
4. Reactivity:
Forms stable metal complexes (via S and N donor atoms).
Undergoes oxidation to disulfides or alkylation reactions.
Applications:
1. Coordination Chemistry:
Ligand for transition metals (e.g., Cu, Ni, Co) in catalysis or material science.
Used to synthesize metal-organic frameworks (MOFs) or catalysts.
2. Organic Synthesis:
Building block for pharmaceuticals (e.g., antiviral or anticancer agents).
Intermediate in the synthesis of heterocyclic compounds.
3. Analytical Chemistry:
Chelating agent for metal ion detection or extraction.
4. Biochemistry:
Modifies proteins/enzymes by reacting with cysteine residues.
Safety & Handling:
Hazards:
Toxic if ingested/inhaled.
Causes skin/eye irritation.
Releases toxic fumes (e.g., SOx) upon combustion.
Precautions:
Use gloves, goggles, and fume hood.
Store in a cool, dry place away from oxidizers.
Disposal: Treat as hazardous waste.
Key Notes:
Its sodium salt (2-mercaptopyridine sodium salt) is more water-soluble and used in biochemical assays.
Contrast with 4-mercaptopyridine (thiol at the 4-position), which has different coordination behavior.
Avoid confusion with 2-mercaptopyridine N-oxide (a distinct antifungal/antibacterial agent).
