Chemical Structure
Description
The molecular framework of 3-(2,4-Dichlorophenyl)-1-(p-tolyl)-1H-pyrazole-4-carbaldehyde (C17H12Cl2N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-(2,4-Dichlorophenyl)-1-(p-tolyl)-1H-pyrazole-4-carbaldehyde (CAS 618098-96-7) is a high-purity analytical reference standard with the molecular formula C17H12Cl2N2O and a molecular weight of 331.20 g/mol.
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.
