Chemical Structure
Description
The occurrence of Lumiflavin-3-acetic Acid Ethyl Ester 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.
CATO supplies Lumiflavin-3-acetic Acid Ethyl Ester (CAS 74178-39-5), a certified reference material (molecular formula C17H18N4O4, MW 342.35 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Lumiflavin-3-acetic Acid Ethyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
