Chemical Structure
Description
CATO supplies Flupirtine maleate (CAS 75507-68-5), a certified reference material (molecular formula C15H17FN4O2C4H4O4, MW 420.40 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Flupirtine maleate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
