Chemical Structure
Description
The occurrence of (S)-2-(((R)-1-(Benzofuran-5-yl)-2-(dimethylamino)-2-oxoethyl)amino)-4-methylpentanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-(((R)-1-(Benzofuran-5-yl)-2-(dimethylamino)-2-oxoethyl)amino)-4-methylpentanoic acid (CAS 821780-06-7) is a high-purity analytical reference standard with the molecular formula C18H24N2O4 and a molecular weight of 332.39 g/mol.
The molecular framework of (S)-2-(((R)-1-(Benzofuran-5-yl)-2-(dimethylamino)-2-oxoethyl)amino)-4-methylpentanoic acid (C18H24N2O4) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (S)-2-(((R)-1-(Benzofuran-5-yl)-2-(dimethylamino)-2-oxoethyl)amino)-4-methylpentanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
