PRODUCT INTRODUCTION
description
N-methylnicotinate is an iminium betaine that is the conjugate base of N-methylnicotinic acid, arising from deprotonation of the carboxy group. It has a role as a plant metabolite, a food component and a human urinary metabolite. It is an iminium betaine and an alkaloid. It is functionally related to a nicotinate. It is a conjugate base of a N-methylnicotinic acid.
