Compared with other compounds in its class, the molecular weight of 553.29 g/mol gives 1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-3-methyl-1H-pyrazole-4-carbonyl}piperazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-3-methyl-1H-pyrazole-4-carbonyl}piperazine (CAS 321534-67-2) is a high-purity analytical reference standard with the molecular formula C21H16Cl2F6N6O and a molecular weight of 553.29 g/mol.
Structurally, 1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-3-methyl-1H-pyrazole-4-carbonyl}piperazine (C21H16Cl2F6N6O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 553.29 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).
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.
