Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-(4-Bromo-6-methyl-3-oxo-3,6-dihydro-2H-pyran-2-yl)-1,3-dimethyl-1H-purine-2,6(3H,9H)-dione.
9-(4-Bromo-6-methyl-3-oxo-3,6-dihydro-2H-pyran-2-yl)-1,3-dimethyl-1H-purine-2,6(3H,9H)-dione (CAS 88375-92-2) is a high-purity analytical reference standard with the molecular formula C13H13BrN4O4 and a molecular weight of 369.17 g/mol.
9-(4-Bromo-6-methyl-3-oxo-3,6-dihydro-2H-pyran-2-yl)-1,3-dimethyl-1H-purine-2,6(3H,9H)-dione (C13H13BrN4O4) contains a nitrogen-containing heterocyclic scaffold, an amide 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. 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 9-(4-Bromo-6-methyl-3-oxo-3,6-dihydro-2H-pyran-2-yl)-1,3-dimethyl-1H-purine-2,6(3H,9H)-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.
