Methyl 5-(4-(methylthio)phenyl)-1-(4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carboxylate CAS 641639-55-6

Description

The occurrence of Methyl 5-(4-(methylthio)phenyl)-1-(4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carboxylate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 5-(4-(methylthio)phenyl)-1-(4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carboxylate (CAS 641639-55-6), molecular formula C19H15F3N2O2S and molecular weight 392.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 5-(4-(methylthio)phenyl)-1-(4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carboxylate (C19H15F3N2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
