PRODUCT INTRODUCTION
description
3-hydroxypicolinic acid is a monohydroxypyridine that is picolinic acid in which the hydrogen at position 3 is replaced by a hydroxy group. It is used as a matrix in matrix-assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of oligonucleotides. It has a role as a MALDI matrix material. It is a monohydroxypyridine and a monocarboxylic acid.
