Chemical Structure

Maytansinol propionate CAS 57103-70-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 621.12 g/mol gives Maytansinol propionate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Maytansinol propionate (CAS 57103-70-5), a certified reference material (molecular formula C31H41ClN2O9, MW 621.12 g/mol) for analytical method development and quality control.

Maytansinol propionate (C31H41ClN2O9) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).

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.
