Pterin-6-carboxylic acid Usage And Synthesis

Uses

Pterine-6-carboxylic Acid is a degradation product of Folic acid (F680300).

Definition

ChEBI: 2-Amino-4-hydroxy-6-pteridinecarboxylic acid is an organooxygen compound and an organonitrogen compound. It is functionally related to an alpha-amino acid.

Purification Methods

The acid gives yellow crystals by repeated dissolution in aqueous NaOH and adding aqueous HCl. It has UV with max at 235, 260 and 265nm ( 11,000, 10,500 and 9,000) in 0.1N HCl and 263 and 365nm ( 20,500 and 9,000) in 0.1N NaOH. [UV: Pfleiderer et al.
