General description

Pyridine (Pyr) is a nitrogen containing six membered heterocyclic compound commonly used as a base. It is a colorless liquid with a fishy odor. Pyridine moiety is present as a major component in a number of compounds like pyridine nucleotides, pyridine alkaloids, pyridine-based polymers and pyridine-containing macrocycles. It has wide application as a solvent, catalyst and as an intermediate for synthesis. IR, Raman and UV spectra of pyridine have been analyzed and the values obtained were used to calculate its thermodynamic properties. Photodegradation and bacterial degradation of Pyr has been studied.
Our biotech solvents offer exceptional quality for reliable RNA extraction, ensuring optimal laboratory performance. With low water content and minimal residue, give clean UV spectra to minimize contamination.
  • High-Quality Biotech Solvents: Designed for optimal laboratory performance with low water content and minimal residues.
  • Ideal for RNA Extraction: Essential for genetic testing and research applications like PCR.
  • Ensures Integrity of Genetic Material: Promotes reliable and reproducible results.
  • Industry Compliant: Suitable for both academic and commercial laboratories, enhancing research efficiency.

Application

Pyridine may be used in the synthesis of the following:
  • complexes with cobalt(II) halides
  • pyridine-d 5, a deuterated form of pyridine
  • ionic liquid matrices (ILMs)
