Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 309.31 g/mol gives Ald-Ph-amido-PEG2-C2-acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ald-Ph-amido-PEG2-C2-acid (CAS 1807534-84-4), a certified reference material (molecular formula C15H19NO6, MW 309.31 g/mol) for analytical method development and quality control.
The molecular framework of Ald-Ph-amido-PEG2-C2-acid (C15H19NO6) 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.
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.
