Chemical Structure
Description
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.
6-(3-Bromophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 33166-82-4) is a high-purity analytical reference standard with the molecular formula C10H7BrN2OS and a molecular weight of 283.14 g/mol.
The molecular framework of 6-(3-Bromophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (C10H7BrN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
