Product remark::
Industrial Usages::
Safety: Pyridine is hazardous and has some unpleasant properties It evaporates into the air very easily It can take several months to years for pyridine to break down into other compounds in the air
Useful Area::
Pyridine is a reasonable nucleophile for carbonyl groups and is often used as a catalyst in acylation reactions. ... The nitrogen atom in pyridine is nucleophilic because the lone pair of electrons on nitrogen cannot be delocalised around the ring.
