⚗️ Chemical & Physical Properties
Picolinic acid is a white crystalline solid with a faint odor. It is commonly found as a powder form and has a mild acidic smell.
With a molar mass of 123.11 g/mol and a density of 1.421 g/cm3, picolinic acid is comparable to common household items such as table salt in terms of molar mass, but slightly denser than water.
Picolinic acid has a melting point of 138-139 °C and a boiling point of 364 °C. Compared to common household items, picolinic acid has a higher melting point than sugar but lower than baking soda. Its boiling point is higher than the boiling point of water.
Picolinic acid is soluble in water and has a low viscosity. In comparison to common household items, it is more soluble in water than oil but less viscous than honey.
🏭 Production & Procurement
Picolinic acid is commonly produced through chemical synthesis, where pyridine is oxidized to form 2,6-dicarboxypyridine, which is then further converted to picolinic acid. This process usually involves several steps and utilizes various reagents and catalysts to achieve the desired product purity.
Picolinic acid can be procured from specialty chemical suppliers or pharmaceutical companies that produce it in bulk quantities. It is typically transported in sealed containers or drums to prevent contamination or degradation during transit. Depending on the scale of production, picolinic acid may also be shipped in intermediate bulk containers or tanker trucks for larger quantities.
In addition to purchasing from suppliers, picolinic acid can also be synthesized in research laboratories or academic institutions for specific studies or experiments. Researchers often follow established protocols or modified procedures to produce picolinic acid in-house, ensuring quality control and cost-effectiveness for their research projects. While the production process may require specialized equipment and expertise, the availability of picolinic acid for research purposes has contributed to its diverse applications in various scientific fields.
