Chemical Structure
Description
The occurrence of 17-Bromo-3,6,9,12,15-pentaoxaheptadecanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
17-Bromo-3,6,9,12,15-pentaoxaheptadecanoic acid (CAS 2098982-48-8), molecular formula C12H23BrO7 and molecular weight 359.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 17-Bromo-3,6,9,12,15-pentaoxaheptadecanoic acid (C12H23BrO7) 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 359.21 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.
