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 5-Bromo-1-methyl-1,3-dihydro-2H-pyrrolo[3,2-b]pyridin-2-one.
5-Bromo-1-methyl-1,3-dihydro-2H-pyrrolo[3,2-b]pyridin-2-one (CAS 2168665-57-2) is a high-purity analytical reference standard with the molecular formula C8H7BrN2O and a molecular weight of 227.06 g/mol.
5-Bromo-1-methyl-1,3-dihydro-2H-pyrrolo[3,2-b]pyridin-2-one (C8H7BrN2O) contains a nitrogen-containing heterocyclic scaffold, 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.
