Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.18 g/mol gives 4-Bromo-2,6-diphenylpyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2,6-diphenylpyrimidine (CAS 40734-24-5) is a high-purity analytical reference standard with the molecular formula C16H11BrN2 and a molecular weight of 311.18 g/mol.
The molecular framework of 4-Bromo-2,6-diphenylpyrimidine (C16H11BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
