3-(1-Methylethyl)-5-[[3-(4-methylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylene]-2-thioxo-4-Thiazolidinone CAS 312601-82-4 chemical structure

Description

The occurrence of 3-(1-Methylethyl)-5-[[3-(4-methylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylene]-2-thioxo-4-Thiazolidinone is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(1-Methylethyl)-5-[[3-(4-methylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylene]-2-thioxo-4-Thiazolidinone (CAS 312601-82-4), molecular formula C23H21N3OS2 and molecular weight 419.56 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(1-Methylethyl)-5-[[3-(4-methylphenyl)-1-phenyl-1H-pyrazol-4-yl]methylene]-2-thioxo-4-Thiazolidinone (C23H21N3OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
