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.
3,3,4,4,4-Pentafluoro-2-hydroxy-2-methylbutyric acid methyl ester (CAS 723294-73-3) is a high-purity analytical reference standard with the molecular formula C6H7F5O3 and a molecular weight of 222.11 g/mol.
3,3,4,4,4-Pentafluoro-2-hydroxy-2-methylbutyric acid methyl ester (C6H7F5O3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
