Chemical Structure

Furo[3,2-d]pyrimidine CAS 4437-16-5 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

Furo[3,2-d]pyrimidine (CAS 4437-16-5), molecular formula C6H4N2O and molecular weight 120.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Furo[3,2-d]pyrimidine (C6H4N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
