Description

Compared with other compounds in its class, the molecular weight of 216.13 g/mol gives 4-Hydroxy-2,3,5,6-tetrafluorobenzoic acid 2,3,5,6-tetrafluoro-4-hydroxybenzoic acid 2,3,5,6-tetrafluoro-4-hydroxy-benzoic acid 652-34-6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Hydroxy-2,3,5,6-tetrafluorobenzoic acid 2,3,5,6-tetrafluoro-4-hydroxybenzoic acid 2,3,5,6-tetrafluoro-4-hydroxy-benzoic acid 652-34-6 (CAS 652-34-6), a certified reference material (molecular formula C7H8F4O3, MW 216.13 g/mol) for analytical method development and quality control.

Structurally, 4-Hydroxy-2,3,5,6-tetrafluorobenzoic acid 2,3,5,6-tetrafluoro-4-hydroxybenzoic acid 2,3,5,6-tetrafluoro-4-hydroxy-benzoic acid 652-34-6 (C7H8F4O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 216.13 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
