Chemical Structure
Description
The occurrence of 7-Bromo-2,4-dichloro-6-iodoquinazoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Bromo-2,4-dichloro-6-iodoquinazoline (CAS 2771459-71-1) is a high-purity analytical reference standard with the molecular formula C8H2BrCl2IN2 and a molecular weight of 403.83 g/mol.
The molecular framework of 7-Bromo-2,4-dichloro-6-iodoquinazoline (C8H2BrCl2IN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine/iodine substitution. 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 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.
As a certified reference material (CRM), 7-Bromo-2,4-dichloro-6-iodoquinazoline 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.
