10,20-Di-O-methoxymethyl SN-38 1246820-40-5 CAS 1246820-40-5 chemical structure

Description

The occurrence of 10,20-Di-O-methoxymethyl SN-38 1246820-40-5 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 10,20-Di-O-methoxymethyl SN-38 1246820-40-5 (CAS 1246820-40-5), a certified reference material (molecular formula C26H28N2O7, MW 480.51 g/mol) for analytical method development and quality control.

The molecular framework of 10,20-Di-O-methoxymethyl SN-38 1246820-40-5 (C26H28N2O7) 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.
