1-(3-Chloro-4-fluorophenyl)-3-phenyl-1H-pyrazole-4-carbaldehyde CAS 618098-80-9

Description

The occurrence of 1-(3-Chloro-4-fluorophenyl)-3-phenyl-1H-pyrazole-4-carbaldehyde 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-(3-Chloro-4-fluorophenyl)-3-phenyl-1H-pyrazole-4-carbaldehyde (CAS 618098-80-9), molecular formula C16H10ClFN2O and molecular weight 300.71 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(3-Chloro-4-fluorophenyl)-3-phenyl-1H-pyrazole-4-carbaldehyde (C16H10ClFN2O) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
