What is 3-Picoline-N-oxide?
Chemical properties
PALE YELLOW TO BROWN CRYSTALLINE LOW MELTING MASS
The Uses of 3-Picoline-N-oxide
An intermediate in the preparation of nicotine derivatives.
Purification Methods
Purify the N-oxide by careful fractionation in vacuo. The distillate remains supercooled for several days before solidifying. It is a slightly hygroscopic solid which could melt in the hand. The picrate has m 149-151o (from EtOH). [Taylor & Corvetti Org Synth Coll Vol IV 654 1963, IR: Katritzky et al.
