5-(1-Buten-1-yl-4-[4-Fluoro-2-(Phenylmethoxy)Phenyl]-2,6-Bis(1-Methylethyl)-3-Pyridinecarboxaldehyde (CAS 503559-81-7), molecular formula C29H32FNO2 and molecular weight 445.57 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C29H32FNO2, 5-(1-Buten-1-yl-4-[4-Fluoro-2-(Phenylmethoxy)Phenyl]-2,6-Bis(1-Methylethyl)-3-Pyridinecarboxaldehyde contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 445.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
