1-Trifluoroacetyl-3-perfluorohexyl-5-(trifluoromethyl)pyrazole CAS 261778-38-5

Description

The occurrence of 1-Trifluoroacetyl-3-perfluorohexyl-5-(trifluoromethyl)pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Trifluoroacetyl-3-perfluorohexyl-5-(trifluoromethyl)pyrazole (CAS 261778-38-5), molecular formula C12HF19N2O and molecular weight 550.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-Trifluoroacetyl-3-perfluorohexyl-5-(trifluoromethyl)pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 550.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
