2,2'-(5-Hydroxy-1,3-phenylene)bis(1,1,1,3,3,3-hexafluoropropan-2-ol) CAS 669768-28-9

Description

2,2'-(5-Hydroxy-1,3-phenylene)bis(1,1,1,3,3,3-hexafluoropropan-2-ol) (CAS 669768-28-9) is a high-purity analytical reference standard with the molecular formula C12H6F12O3 and a molecular weight of 426.16 g/mol.

The molecular framework of 2,2'-(5-Hydroxy-1,3-phenylene)bis(1,1,1,3,3,3-hexafluoropropan-2-ol) (C12H6F12O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
