Chemical Structure
Description
The occurrence of 6-bromo-3-propyl-2,4(1H,3H)-quinazolinedione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-bromo-3-propyl-2,4(1H,3H)-quinazolinedione (CAS 200938-70-1), molecular formula C11H11BrN2O2 and molecular weight 283.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-3-propyl-2,4(1H,3H)-quinazolinedione (C11H11BrN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 6-bromo-3-propyl-2,4(1H,3H)-quinazolinedione 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.
