Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 202.05 g/mol gives 5-Bromo-2-(dimethylamino)pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-(dimethylamino)pyrimidine (CAS 38696-21-8) is a high-purity analytical reference standard with the molecular formula C6H8BrN3 and a molecular weight of 202.05 g/mol.
The molecular framework of 5-Bromo-2-(dimethylamino)pyrimidine (C6H8BrN3) is characterized by a nitrile group, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
As a certified reference material (CRM), 5-Bromo-2-(dimethylamino)pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
