7-Chloro-3-[4-(2-hydroxyethyl)piperazin-1-yl]-1-(2-propoxyethyl)-1H,2H-pyrido[3,4-b]pyrazin-2-one CAS 954138-53-5

Description

CATO supplies 7-Chloro-3-[4-(2-hydroxyethyl)piperazin-1-yl]-1-(2-propoxyethyl)-1H,2H-pyrido[3,4-b]pyrazin-2-one (CAS 954138-53-5), a certified reference material (molecular formula C18H26ClN5O3, MW 395.88 g/mol) for analytical method development and quality control.

The molecular framework of 7-Chloro-3-[4-(2-hydroxyethyl)piperazin-1-yl]-1-(2-propoxyethyl)-1H,2H-pyrido[3,4-b]pyrazin-2-one (C18H26ClN5O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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.
