1-(2,3,4,6-Tetrakis-O-benzyl)-2,3-bis(tert-butyldimethylsilyloxy) KRN7000 CAS 205371-69-3 chemical structure

Description

The occurrence of 1-(2,3,4,6-Tetrakis-O-benzyl)-2,3-bis(tert-butyldimethylsilyloxy) KRN7000 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2,3,4,6-Tetrakis-O-benzyl)-2,3-bis(tert-butyldimethylsilyloxy) KRN7000 (CAS 205371-69-3) is a high-purity analytical reference standard with the molecular formula C90H151NO9Si2 and a molecular weight of 1447.33 g/mol.

The molecular framework of 1-(2,3,4,6-Tetrakis-O-benzyl)-2,3-bis(tert-butyldimethylsilyloxy) KRN7000 (C90H151NO9Si2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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).

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.

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.
