Description

Compared with other compounds in its class, the molecular weight of 279.29 g/mol gives 5-Methyl-1-(2-nitrophenyl)-3-phenyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Methyl-1-(2-nitrophenyl)-3-phenyl-1H-pyrazole (CAS 29334-69-8) is a high-purity analytical reference standard with the molecular formula C16H13N3O2 and a molecular weight of 279.29 g/mol.

The molecular framework of 5-Methyl-1-(2-nitrophenyl)-3-phenyl-1H-pyrazole (C16H13N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
