Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, (5r)-5-(bromomethyl)pyrrolidin-2-one (R)-5-Bromomethyl-2-pyrrolidinone (r)-5-(bromomethyl)pyrrolidin-2-one 2-pyrrolidinone, 5-(bromomethyl)-, (5r)- 98612-60-3 [r,(+)]-5|A-(bromomethyl)pyrrolidine-2-one [r,(+)]-5|A-bromomethyl-2-pyrrolidone b50370 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(5r)-5-(bromomethyl)pyrrolidin-2-one (R)-5-Bromomethyl-2-pyrrolidinone (r)-5-(bromomethyl)pyrrolidin-2-one 2-pyrrolidinone, 5-(bromomethyl)-, (5r)- 98612-60-3 [r,(+)]-5|A-(bromomethyl)pyrrolidine-2-one [r,(+)]-5|A-bromomethyl-2-pyrrolidone b50370 (CAS 98612-60-3), molecular formula C5H8BrNO and molecular weight 178.03 g/mol, is a CATO reference standard with documented purity and traceability.
