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.
351003-31-1 CTK4H3623 Methanone,(4-ethoxyphenyl)(pentafluorophenyl)- (9CI) (CAS 351003-31-1), molecular formula C15H9F5O2 and molecular weight 316.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 351003-31-1 CTK4H3623 Methanone,(4-ethoxyphenyl)(pentafluorophenyl)- (9CI) (C15H9F5O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 316.22 g/mol, it falls into the moderately-high-molecular-weight range. 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.
