Chemical Structure

2,7-Dipropyl-1,4-dihydropyrimido[4,5-d]pyrimidine CAS 720-68-3 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.

CATO supplies 2,7-Dipropyl-1,4-dihydropyrimido[4,5-d]pyrimidine (CAS 720-68-3), a certified reference material (molecular formula C12H18N4, MW 218.30 g/mol) for analytical method development and quality control.

The molecular framework of 2,7-Dipropyl-1,4-dihydropyrimido[4,5-d]pyrimidine (C12H18N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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