Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(3-Phenyl-4,5-dihydro-1H-pyrazole-1-carbonothioyl)benzamide (CAS 89652-19-7) is a high-purity analytical reference standard with the molecular formula C17H15N3OS and a molecular weight of 309.39 g/mol.
The molecular framework of N-(3-Phenyl-4,5-dihydro-1H-pyrazole-1-carbonothioyl)benzamide (C17H15N3OS) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
