5-((4-Fluorophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbonitrile CAS 321998-37-2

Description

5-((4-Fluorophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbonitrile (CAS 321998-37-2), molecular formula C17H12FN3S and molecular weight 309.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-((4-Fluorophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbonitrile (C17H12FN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 309.36 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
