7-Propyl-1,7-dihydropyrimido[4,5-d]pyrimidine-2,4,7-triamine CAS 118801-61-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Propyl-1,7-dihydropyrimido[4,5-d]pyrimidine-2,4,7-triamine.

7-Propyl-1,7-dihydropyrimido[4,5-d]pyrimidine-2,4,7-triamine (CAS 118801-61-9), molecular formula C9H15N7 and molecular weight 221.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Propyl-1,7-dihydropyrimido[4,5-d]pyrimidine-2,4,7-triamine (C9H15N7) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.

CATO manufactures 7-Propyl-1,7-dihydropyrimido[4,5-d]pyrimidine-2,4,7-triamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
