Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.20 g/mol gives 2,2-Difluoro-5-isopropylcyclohexane-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,2-Difluoro-5-isopropylcyclohexane-1,3-dione (CAS 1031926-87-0), a certified reference material (molecular formula C9H12F2O2H2O, MW 208.20 g/mol) for analytical method development and quality control.
2,2-Difluoro-5-isopropylcyclohexane-1,3-dione (C9H12F2O2H2O) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
