Chemical Structure
Description
tert-Butyl(5-chloro-2-fluorophenoxy)dimethylsilane (CAS 1881296-20-3), molecular formula C12H18ClFOSi and molecular weight 260.81 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-Butyl(5-chloro-2-fluorophenoxy)dimethylsilane (C12H18ClFOSi) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 260.81 g/mol, it falls into the medium-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.
