Chemical Structure
Description
The molecular framework of 1-(2,2-Dimethyltetrahydro-2H-thiopyran-4-yl)-3-phenyl-1H-pyrazol-5(4H)-one (C16H20N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(2,2-Dimethyltetrahydro-2H-thiopyran-4-yl)-3-phenyl-1H-pyrazol-5(4H)-one (CAS 102689-17-8) is a high-purity analytical reference standard with the molecular formula C16H20N2OS and a molecular weight of 288.41 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.
