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 2-bromo-1-(3-oxabicyclo[3.1.0]hexan-6-yl)ethanone.
2-bromo-1-(3-oxabicyclo[3.1.0]hexan-6-yl)ethanone (CAS 1858653-58-3) is a high-purity analytical reference standard with the molecular formula C7H9BrO2 and a molecular weight of 205.05 g/mol.
Structurally, 2-bromo-1-(3-oxabicyclo[3.1.0]hexan-6-yl)ethanone (C7H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 205.05 g/mol, it falls into the medium-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
