Description
(2E)-3-{4-[(2,4-dichlorophenyl)methoxy]phenyl}-1-{3-[1-({2-fluoro-[1,1'-biphenyl]-4-yl}oxy)ethyl]-1H-pyrazol-1-yl}prop-2-en-1-one (CAS 477710-97-7), molecular formula C33H25Cl2FN2O3 and molecular weight 587.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2E)-3-{4-[(2,4-dichlorophenyl)methoxy]phenyl}-1-{3-[1-({2-fluoro-[1,1'-biphenyl]-4-yl}oxy)ethyl]-1H-pyrazol-1-yl}prop-2-en-1-one (C33H25Cl2FN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 587.47 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
