Chemical Properties

Light yellow Needles

Uses

3-Hydroxypicolinic acid (3-HPA) is a matrix material used in matrix-assisted laser desorption/ionization (MALDI) based mass spectroscopy (MS) for the analysis of large biomolecules and quantification of oligonucleotides.

Definition

ChEBI: 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.
