Chemical Structure

(1-(tert-butoxycarbonyl)-5-(((isopropyldimethylsilyl)oxy)methyl)-1H-indol-2-yl)boronic acid CAS 503045-89-4 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

(1-(tert-butoxycarbonyl)-5-(((isopropyldimethylsilyl)oxy)methyl)-1H-indol-2-yl)boronic acid (CAS 503045-89-4) is a high-purity analytical reference standard with the molecular formula C19H30BNO5Si and a molecular weight of 391.34 g/mol.

(1-(tert-butoxycarbonyl)-5-(((isopropyldimethylsilyl)oxy)methyl)-1H-indol-2-yl)boronic acid (C19H30BNO5Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

CATO manufactures (1-(tert-butoxycarbonyl)-5-(((isopropyldimethylsilyl)oxy)methyl)-1H-indol-2-yl)boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
