6-(4-Nitrophenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine CAS 338791-45-0

Description

6-(4-Nitrophenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine (CAS 338791-45-0), molecular formula C13H13N5O2 and molecular weight 271.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-(4-Nitrophenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine (C13H13N5O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

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 6-(4-Nitrophenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine 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.
