Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Iron, [[4,4′,4′′,4′′′-(21H,23H-porphine-5,10,15,20-tetrayl-κN21,κN22,κN23,κN24)tetrakis[benzenaminato]](2-)]-, (SP-4-1)- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 728.62 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).
CATO supplies Iron, [[4,4′,4′′,4′′′-(21H,23H-porphine-5,10,15,20-tetrayl-κN21,κN22,κN23,κN24)tetrakis[benzenaminato]](2-)]-, (SP-4-1)- (CAS 71547-22-3), a certified reference material (molecular formula C44H32FeN8, MW 728.62 g/mol) for analytical method development and quality control.
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.
