Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 487.06 g/mol gives 231301-30-7 1-Acetyl-4-bromo-3(5)-[tetrafluoro-1-(heptafluoro-1-propoxyethyl)]-5(3)-(methyl)pyrazole MFCD00153617 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
231301-30-7 1-Acetyl-4-bromo-3(5)-[tetrafluoro-1-(heptafluoro-1-propoxyethyl)]-5(3)-(methyl)pyrazole MFCD00153617 (CAS 231301-30-7) is a high-purity analytical reference standard with the molecular formula C11H6BrF11N2O2 and a molecular weight of 487.06 g/mol.
231301-30-7 1-Acetyl-4-bromo-3(5)-[tetrafluoro-1-(heptafluoro-1-propoxyethyl)]-5(3)-(methyl)pyrazole MFCD00153617 (C11H6BrF11N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
