About Pyridine, for HPLC 99%+

Pyridine is an HPLC grade solvent in HPLC grade carrying the CAS registry number 110-86-1 with a typical assay of ≥99%. Its molecular formula is C5H5N and its molecular weight is 79.1 g/mol. It is also known as Azine or Azabenzene.

The material typically appears as a colourless liquid. Reported physical data include a melting point of -41.6 °C and a boiling point of 115 °C. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

Typical applications include HPLC mobile phase, LC-MS sample preparation, trace analysis and chromatography. Buyers come mainly from academic and industrial research and pharmaceutical manufacturing.

We offer Pyridine in 500 mL, 5 L and 200 kg packs with a batch-specific COA, and ship to customers worldwide.
