Chemical Structure
Description
(S)-1-(tert-Butoxycarbonyl)-4-(2-formyl-5-nitrophenyl)piperazine-2-carboxylic acid 1786500-32-0 (CAS 1786500-32-0) is a high-purity analytical reference standard with the molecular formula C17H21N3O7 and a molecular weight of 379.36 g/mol.
The molecular framework of (S)-1-(tert-Butoxycarbonyl)-4-(2-formyl-5-nitrophenyl)piperazine-2-carboxylic acid 1786500-32-0 (C17H21N3O7) is characterized by a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
