N1-(5-Ethyl-1,2,3,4-tetrahydropyrimido[4',5':4,5]thieno[2,3-c]isoquinolin-8-yl)-N2,N2-dimethylethane-1,2-diamine CAS 372171-81-8

Description

The molecular framework of N1-(5-Ethyl-1,2,3,4-tetrahydropyrimido[4',5':4,5]thieno[2,3-c]isoquinolin-8-yl)-N2,N2-dimethylethane-1,2-diamine (C19H25N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

N1-(5-Ethyl-1,2,3,4-tetrahydropyrimido[4',5':4,5]thieno[2,3-c]isoquinolin-8-yl)-N2,N2-dimethylethane-1,2-diamine (CAS 372171-81-8) is a high-purity analytical reference standard with the molecular formula C19H25N5S and a molecular weight of 355.50 g/mol.

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.

As a certified reference material (CRM), N1-(5-Ethyl-1,2,3,4-tetrahydropyrimido[4',5':4,5]thieno[2,3-c]isoquinolin-8-yl)-N2,N2-dimethylethane-1,2-diamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
