((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)trimethylsilane (CAS 1998128-14-5), molecular formula C12H20O2Si and molecular weight 224.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)trimethylsilane (C12H20O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
