It is also used to prepare dipicolinato ligated lanthanide and transition metal complexes for ion chromatography.

[6] Two genera of bacterial pathogens are known to produce endospores: the aerobic Bacillus and anaerobic Clostridium.

[10] Simple substituted pyridines vary significantly in environmental fate characteristics, such as volatility, adsorption, and biodegradation.

[11] Dipicolinic acid is among the least volatile, least adsorbed by soil, and most rapidly degraded of the simple pyridines.

[12] A number of studies have confirmed dipicolinic acid is biodegradable in aerobic and anaerobic environments, which is consistent with the widespread occurrence of the compound in nature.
