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.
5-(4-Bromophenyl)-6-ethylpyrimidine-2,4-diamine (CAS 763-11-1) is a high-purity analytical reference standard with the molecular formula C12H13BrN4 and a molecular weight of 293.16 g/mol.
The molecular framework of 5-(4-Bromophenyl)-6-ethylpyrimidine-2,4-diamine (C12H13BrN4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
