2 '-O-Benzoyl-3-O-de [(2,6-dideoxy-3-c-methyl-3-O-methyl-a-L-ribohexopyranosyl)oxy]-11-deoxy-10,11-didehydro-6-O-methyl-3-oxoerythromycin CAS 160145-82-4 chemical structure

Description

The occurrence of 2 '-O-Benzoyl-3-O-de [(2,6-dideoxy-3-c-methyl-3-O-methyl-a-L-ribohexopyranosyl)oxy]-11-deoxy-10,11-didehydro-6-O-methyl-3-oxoerythromycin 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.

CATO supplies 2 '-O-Benzoyl-3-O-de [(2,6-dideoxy-3-c-methyl-3-O-methyl-a-L-ribohexopyranosyl)oxy]-11-deoxy-10,11-didehydro-6-O-methyl-3-oxoerythromycin (CAS 160145-82-4), a certified reference material (molecular formula C37H55NO10, MW 673.83 g/mol) for analytical method development and quality control.

The molecular framework of 2 '-O-Benzoyl-3-O-de [(2,6-dideoxy-3-c-methyl-3-O-methyl-a-L-ribohexopyranosyl)oxy]-11-deoxy-10,11-didehydro-6-O-methyl-3-oxoerythromycin (C37H55NO10) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
