⚗️ Chemical & Physical Properties
Pyridine is a colorless liquid with a pungent, fish-like odor. It is highly soluble in water and has a boiling point of 115.2 Celsius and a melting point of -41.6 Celsius.
The molar mass of Pyridine is approximately 80.1 g/mol, and its density is about 0.982 g/cm³. When compared to common household items, Pyridine has a higher molar mass and a lower density than water, which has a molar mass of 18.015 g/mol and a density of 1 g/cm³.
Pyridine’s melting point and boiling point are lower than those of many common household items. For example, the melting point of Pyridine is much lower than that of ice (0 Celsius), and the boiling point of Pyridine is significantly lower than that of water (100 Celsius).
Pyridine is soluble in water, forming a homogenous solution, and has a relatively low viscosity. When compared to common household items, Pyridine’s solubility in water is similar to that of alcohol, and its viscosity is comparable to that of vinegar.
🏭 Production & Procurement
Pyridine, an organic compound with the chemical formula C5H5N, is primarily produced through the reaction of acetaldehyde and ammonia in the presence of a catalyst. This process results in the formation of pyridine, an important solvent and precursor in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds.
Pyridine can be procured through various methods, including synthesis in chemical plants and extraction from coal tar or crude oil. Once produced, pyridine is typically transported in liquid form in bulk tankers or drums to ensure its safe delivery to various industries. The compound’s flammable nature requires careful handling and adherence to safety regulations during transportation.
⚠️ Safety Considerations
Safety considerations for Pyridine primarily revolve around its flammable nature. Pyridine is highly flammable in its liquid form, with a flashpoint of 17°C. It also poses a risk of explosion when exposed to heat or flame.
Additionally, Pyridine is also considered to be harmful if swallowed, inhaled, or absorbed through the skin. It can cause irritation to the respiratory system, skin, and eyes. Therefore, proper personal protective equipment should be worn when handling Pyridine to prevent any potential exposure.
In terms of pharmacology, Pyridine is a basic heterocyclic organic compound. It is commonly used as a solvent in chemical reactions and as a precursor in the synthesis of pharmaceuticals. Pyridine is known to have a distinct odor and is readily soluble in water, making it a versatile compound in various industrial applications.
Hazard statements for Pyridine include flammable liquid and vapor, harmful if swallowed, toxic to aquatic life with long-lasting effects, and may cause respiratory irritation. Pyridine should be handled with caution and stored in a well-ventilated area away from sources of ignition to prevent any potential hazards.
Precautionary statements for Pyridine recommend avoiding breathing in vapors, wearing protective gloves and eye protection, and keeping away from heat/sparks/open flames/hot surfaces. It is also important to dispose of Pyridine properly and not release it into the environment. In case of exposure, seek medical advice immediately and provide the Safety Data Sheet to medical personnel.
🔬 Potential Research Directions
One potential research direction for pyridine is its use as a building block in the synthesis of pharmaceuticals and agrochemicals due to its structural versatility and importance in biological activities.
Furthermore, the development of novel synthetic methodologies utilizing pyridine derivatives can lead to the discovery of new compounds with medicinal properties, providing opportunities for drug discovery and development.

🧪 Related Compounds
One class of compounds similar to pyridine based upon molecular structure is the pyrimidine derivatives. Pyrimidine is a six-membered heterocyclic ring containing two nitrogen atoms at positions 1 and 3. These derivatives share the same structural feature of a six-membered ring with at least two nitrogen atoms incorporated within the ring system.
Another group of compounds that bear structural similarity to pyridine are the quinoline derivatives. Quinoline consists of a fused ring system containing a benzene ring and a pyridine ring. This structural characteristic of a fused heterocyclic ring system distinguishes quinoline derivatives from simple pyridine compounds, while maintaining the presence of the nitrogen atom within the ring structure.
Isoquinoline derivatives represent another class of compounds that exhibit structural resemblance to pyridine. Isoquinoline contains a benzene ring fused with a pyridine ring, similar to quinoline. However, in the case of isoquinoline, the nitrogen atom is shifted to a different position within the fused ring system, providing a unique structural variation while maintaining the fundamental features of pyridine-based compounds.
