Chemical Structure
Description
The occurrence of (S)-4-(3-Bromo-6-formylphenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786898-74-5 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-4-(3-Bromo-6-formylphenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786898-74-5 (CAS 1786898-74-5), molecular formula C17H21BrN2O5 and molecular weight 413.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-4-(3-Bromo-6-formylphenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786898-74-5 (C17H21BrN2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
