Chemical Structure
Description
6-Amino-5-bromopyrimidine-2,4(1H,3H)-dione (CAS 6312-73-8) is a high-purity analytical reference standard with the molecular formula C4H4BrN3O2 and a molecular weight of 206.00 g/mol.
The molecular framework of 6-Amino-5-bromopyrimidine-2,4(1H,3H)-dione (C4H4BrN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6-Amino-5-bromopyrimidine-2,4(1H,3H)-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
