5-((4-Chlorophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbaldehyde CAS 318247-49-3

Description

The molecular framework of 5-((4-Chlorophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbaldehyde (C17H13ClN2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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).

5-((4-Chlorophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbaldehyde (CAS 318247-49-3), molecular formula C17H13ClN2OS and molecular weight 328.82 g/mol, is a CATO reference standard with documented purity and traceability.

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.
