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 (2R)-3-Bromo-5-oxopyrrolidine-2-carboxylic hexanoic anhydride.
(2R)-3-Bromo-5-oxopyrrolidine-2-carboxylic hexanoic anhydride (CAS 60633-80-9) is a high-purity analytical reference standard with the molecular formula C9H15BrO3 and a molecular weight of 251.12 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, (2R)-3-Bromo-5-oxopyrrolidine-2-carboxylic hexanoic anhydride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.12 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.
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.
