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 (E)-7-[5-[[[(1,1-Dimethylethyl)dimethylsilyl]oxy]methyl]-4-(4-fluorophenyl)-2,6-bis(1-methylethyl)-3-pyridinyl]-5-hydroxy-3-oxo-6-heptenoic Acid Methyl Ester 124863-85-0 Methyl rac-(E)-7-[5-tert-Butyldimethylsilyloxymethyl-2,6-diisopropyl-4-(4-fluorophenyl)-3-pyridinyl]-5-hydroxy-3-oxo-6-heptenoate (CAS 124863-85-0), a certified reference material (molecular formula C32H46FNO5Si, MW 571.80 g/mol) for analytical method development and quality control.
Structurally, (E)-7-[5-[[[(1,1-Dimethylethyl)dimethylsilyl]oxy]methyl]-4-(4-fluorophenyl)-2,6-bis(1-methylethyl)-3-pyridinyl]-5-hydroxy-3-oxo-6-heptenoic Acid Methyl Ester 124863-85-0 Methyl rac-(E)-7-[5-tert-Butyldimethylsilyloxymethyl-2,6-diisopropyl-4-(4-fluorophenyl)-3-pyridinyl]-5-hydroxy-3-oxo-6-heptenoate (C32H46FNO5Si) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 571.80 g/mol, it falls into the moderately-high-molecular-weight range. 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.
