1-(4-Fluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde CAS 618101-62-5

Description

The occurrence of 1-(4-Fluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde 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.

1-(4-Fluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618101-62-5) is a high-purity analytical reference standard with the molecular formula C16H10FN3O3 and a molecular weight of 311.27 g/mol.

The molecular framework of 1-(4-Fluorophenyl)-3-(4-nitrophenyl)-1H-pyrazole-4-carbaldehyde (C16H10FN3O3) 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).

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.
