5-amino-1-(4-fluorophenyl)-3-methyl-1H-pyrazole-4-carboxamide CAS 51516-81-5

Description

The occurrence of 5-amino-1-(4-fluorophenyl)-3-methyl-1H-pyrazole-4-carboxamide 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.

5-amino-1-(4-fluorophenyl)-3-methyl-1H-pyrazole-4-carboxamide (CAS 51516-81-5) is a high-purity analytical reference standard with the molecular formula C11H11FN4O and a molecular weight of 234.23 g/mol.

The molecular framework of 5-amino-1-(4-fluorophenyl)-3-methyl-1H-pyrazole-4-carboxamide (C11H11FN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
