Chemical Structure
Description
The occurrence of Dimethyl 4,4'-(perfluoropropane-2,2-diyl)dibenzoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dimethyl 4,4'-(perfluoropropane-2,2-diyl)dibenzoate (CAS 32636-85-4) is a high-purity analytical reference standard with the molecular formula C19H14F6O4 and a molecular weight of 420.30 g/mol.
Structurally, Dimethyl 4,4'-(perfluoropropane-2,2-diyl)dibenzoate (C19H14F6O4) contains a flavonoid core, 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 420.30 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.
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.
