Chemical Structure

Pteridine-4,7-diol CAS 33669-70-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Pteridine-4,7-diol (CAS 33669-70-4) is a high-purity analytical reference standard with the molecular formula C6H4N4O2 and a molecular weight of 164.12 g/mol.

The molecular framework of Pteridine-4,7-diol (C6H4N4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Pteridine-4,7-diol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
