(4-((4-(2-((Tert-butyldimethylsilyl)oxy)ethyl)piperazin-1-yl)sulfonyl)phenyl)boronic acid (CAS 1704065-54-2) is a high-purity analytical reference standard with the molecular formula C18H33BN2O5SSi and a molecular weight of 428.43 g/mol.
The molecular framework of (4-((4-(2-((Tert-butyldimethylsilyl)oxy)ethyl)piperazin-1-yl)sulfonyl)phenyl)boronic acid (C18H33BN2O5SSi) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
