Chemical Structure
Description
The molecular framework of 1243091-65-7 1-(4-Benzyl-3-oxo-3,4-dihydropyrido[2,3-b]pyrazin-2-yl)piperidine-4-carboxylic acid MFCD15732183 (C20H20N4O3) is characterized by a steroid core, 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).
CATO supplies 1243091-65-7 1-(4-Benzyl-3-oxo-3,4-dihydropyrido[2,3-b]pyrazin-2-yl)piperidine-4-carboxylic acid MFCD15732183 (CAS 1243091-65-7), a certified reference material (molecular formula C20H20N4O3, MW 364.40 g/mol) for analytical method development and quality control.
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.
