Product Overview

Product Name: Pyridine 

CAS No.: 110-86-1

Molecular Formula: C₅H₅N

Molecular Weight: 79.10 

EINECS No.: 203-809-9 

Synonyms: Azine, Pyridine

Pyridine (CAS 110-86-1) is a basic heterocyclic organic compound that belongs to the aromatic family. Structurally, it resembles benzene but with one CH group replaced by a nitrogen atom . It appears as a colorless to light yellow liquid with a characteristic strong, unpleasant fishy odor . The name "pyridine" derives from the Greek word "pyro," meaning fire, a nod to its high flammability .

With a purity of ≥99.9%, pyridine is a versatile chemical with an estimated dipole moment of 3.61 D and complete miscibility with water . It possesses a conjugated system of six π-electrons delocalized over its planar ring structure, confirming its aromatic nature per Hückel's rule . The compound acts as a weak base (pKa ~5.23) due to the lone pair of electrons on the nitrogen atom projecting outward from the ring, which does not participate in the aromatic system

Key Applications:

1. Pharmaceutical Synthesis (Primary Application)

Pyridine is a critical raw material and intermediate in the pharmaceutical industry. It is used in the synthesis of numerous active pharmaceutical ingredients (APIs) including sulfonamide drugs, penicillin, vitamin A, cortisone, anthelmintics, and local anesthetics . It also serves as a solvent and catalyst in various pharmaceutical reactions .

2. Agrochemical Industry

Used extensively in the production of herbicides, insecticides, and other pesticide intermediates . Pyridine derivatives are essential building blocks for modern crop protection products.

3. Organic Synthesis & Solvent

Acts as an excellent solvent for many organic and inorganic compounds, capable of dissolving a wide range of substances . It is widely used as a solvent in Knoevenagel condensation reactions and as a base in various organic transformations .

4. Analytical Chemistry

Used as a reagent for the determination of numerous elements including antimony, arsenic, aluminum, bismuth, cadmium, cerium, chromium, cobalt, copper, gold, lead, lithium, manganese, mercury, nickel, platinum, silver, sulfur, thallium, titanium, uranium, vanadium, zinc, and zirconium . Also employed as a reference substance in chromatographic analysis .

5. Industrial Applications
