1-Phenyl-5-(trifluoromethyl)pyrazole-4-carbonylchloride CAS 175137-14-1

Description

The occurrence of 1-Phenyl-5-(trifluoromethyl)pyrazole-4-carbonylchloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Phenyl-5-(trifluoromethyl)pyrazole-4-carbonylchloride (CAS 175137-14-1) is a high-purity analytical reference standard with the molecular formula C11H6ClF3N2O and a molecular weight of 274.63 g/mol.

The molecular framework of 1-Phenyl-5-(trifluoromethyl)pyrazole-4-carbonylchloride (C11H6ClF3N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
