About Pyridine, GR 99%+

Vaqora Chemicals supplies Pyridine in AR grade, an analytical reagent grade solvent registered under CAS number 110-86-1 with a typical assay of ≥99%. With the molecular formula C5H5N, it has a molar mass of 79.1 g/mol. It is also known as Azine or Azabenzene.

In its supplied form it is a liquid colourless to yellow liquid. Literature values give a density of 0.9819 g/ml. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include analytical reagent work, extraction and recrystallisation, titrimetric analysis and solvent and extraction work. Our customers for this product work in academic and industrial research and pharmaceutical manufacturing.

Vaqora Chemicals supplies Pyridine in 500 mL, 5 L, 25 kg and 160 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
