1-(4-Bromo-5-phenyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)ethan-1-one (CAS 808764-25-2) is a high-purity analytical reference standard with the molecular formula C12H8BrF3N2O and a molecular weight of 333.10 g/mol.
Structurally, 1-(4-Bromo-5-phenyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)ethan-1-one (C12H8BrF3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 333.10 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 1-(4-Bromo-5-phenyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)ethan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
