Chemical Structure
Description
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.
(1-(tert-butoxycarbonyl)-6-(((tert-butyldimethylsilyl)oxy)methyl)-1H-indol-2-yl)boronic acid (CAS 501364-51-8) is a high-purity analytical reference standard with the molecular formula C20H32BNO5Si and a molecular weight of 405.37 g/mol.
The molecular framework of (1-(tert-butoxycarbonyl)-6-(((tert-butyldimethylsilyl)oxy)methyl)-1H-indol-2-yl)boronic acid (C20H32BNO5Si) is characterized by a steroid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
