Description
Compared with other compounds in its class, the molecular weight of 541.47 g/mol gives Prop-2-yn-1-yl 3-((2-bromo-2-methylpropanoyl)oxy)-2-(((3-((3-ethoxy-3-oxopropyl)disulfanyl)propanoyl)oxy)methyl)-2-methylpropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Prop-2-yn-1-yl 3-((2-bromo-2-methylpropanoyl)oxy)-2-(((3-((3-ethoxy-3-oxopropyl)disulfanyl)propanoyl)oxy)methyl)-2-methylpropanoate (CAS 1772624-47-1) is a high-purity analytical reference standard with the molecular formula C20H29BrO8S2 and a molecular weight of 541.47 g/mol.
Structurally, Prop-2-yn-1-yl 3-((2-bromo-2-methylpropanoyl)oxy)-2-(((3-((3-ethoxy-3-oxopropyl)disulfanyl)propanoyl)oxy)methyl)-2-methylpropanoate (C20H29BrO8S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 541.47 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
