Description
(2,4,6,8-Tetramethyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane-2,4,6,8-tetrayl)tetrakis(propane-3,1-diyl) tetraacrylate (CAS 71550-64-6), molecular formula C28H48O12Si4 and molecular weight 689.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2,4,6,8-Tetramethyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane-2,4,6,8-tetrayl)tetrakis(propane-3,1-diyl) tetraacrylate (C28H48O12Si4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 689.02 g/mol, it falls into the 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.
