YELLOW-BEIGE CRYSTALLINE POWDER
The Uses of 2-Amino-4-hydroxy-1H-pteridine
Pterin is used in the biosynthesis and metabolism of tetrahydrobiopterin and molybdopterin.
Definition
ChEBI: 2-aminopteridin-4-ol is a 2-amino-4-hydroxypteridine. It is a tautomer of a 2-aminopteridin-4(3H)-one and a 2-aminopteridin-4(1H)-one.
Purification Methods
It is dissolved in hot 1% aqueous ammonia, filtered, and an equal volume of hot 1M aqueous formic acid is added. The solution is allowed to cool at 0-2o overnight. The solid is collected and washed with distilled water several times by centrifugation and dried in vacuo over P2O5 overnight, and then at 100o overnight (any ammonium formate in the sample evaporates off).
