Chemical Structure
Description
The occurrence of 5-Amino-3-hydroxypicolinic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Amino-3-hydroxypicolinic acid (CAS 856835-10-4) is a high-purity analytical reference standard with the molecular formula C6H6N2O3 and a molecular weight of 154.12 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-Amino-3-hydroxypicolinic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
