Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 329.18 g/mol gives Bromo-PEG4-acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bromo-PEG4-acid (CAS 1393330-38-5) is a high-purity analytical reference standard with the molecular formula C11H21BrO6 and a molecular weight of 329.18 g/mol.
Structurally, Bromo-PEG4-acid (C11H21BrO6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 329.18 g/mol, it falls into the moderately-high-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.
