Chemical Structure
Description
The occurrence of 6-Amino-5-bromo-1-methylpyrimidine-2,4(1H,3H)-dione hydrate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Amino-5-bromo-1-methylpyrimidine-2,4(1H,3H)-dione hydrate (CAS 1052403-74-3), molecular formula C5H6BrN3O2H2O and molecular weight 238.04 g/mol, is a CATO reference standard with documented purity and traceability.
6-Amino-5-bromo-1-methylpyrimidine-2,4(1H,3H)-dione hydrate (C5H6BrN3O2H2O) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
