Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-bromo-2-methyl-1H-pyrimidin-6-one.
CATO supplies 5-bromo-2-methyl-1H-pyrimidin-6-one (CAS 1676-57-9), a certified reference material (molecular formula C5H9BrN2O, MW 193.04 g/mol) for analytical method development and quality control.
5-bromo-2-methyl-1H-pyrimidin-6-one (C5H9BrN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
