Chemical Structure
Description
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.
CATO supplies 1G4W8NR1PT 22293-47-6 Feprosidnine [INN] Sydnophen 3-(alpha-Methylphenethyl)sydnone imine 3-(1-Methyl-2-phenylethyl)sydnone imine, monohydrochloride Feprosidnina [INN-Spanish] Feprosidninum [INN-Latin] Feprosidnina Feprosidninum UNII-1G4W8NR1PT Feprosidnine (CAS 22293-47-6), a certified reference material (molecular formula C11H13N3O, MW 203.24 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1G4W8NR1PT 22293-47-6 Feprosidnine [INN] Sydnophen 3-(alpha-Methylphenethyl)sydnone imine 3-(1-Methyl-2-phenylethyl)sydnone imine, monohydrochloride Feprosidnina [INN-Spanish] Feprosidninum [INN-Latin] Feprosidnina Feprosidninum UNII-1G4W8NR1PT Feprosidnine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 203.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
