Chemical Structure
Description
The occurrence of 2,5-Dioxopyrrolidin-1-yl 1-bromo-3-methyl-2-oxo-6,9,12,15-tetraoxa-3-azaoctadecan-18-oate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,5-Dioxopyrrolidin-1-yl 1-bromo-3-methyl-2-oxo-6,9,12,15-tetraoxa-3-azaoctadecan-18-oate (CAS 1283658-70-7), a certified reference material (molecular formula C18H29BrN2O9, MW 497.33 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H29BrN2O9, 2,5-Dioxopyrrolidin-1-yl 1-bromo-3-methyl-2-oxo-6,9,12,15-tetraoxa-3-azaoctadecan-18-oate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 497.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
