Chemical Structure

11 beta-Hydroxy-17,20:20,21-bis(methylenedioxy)pregn-4-en-3-one CAS 1419705-13-7 chemical structure

Description

11 beta-Hydroxy-17,20:20,21-bis(methylenedioxy)pregn-4-en-3-one (C18H36NO5P) contains an amide group, a phosphate ester group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 11 beta-Hydroxy-17,20:20,21-bis(methylenedioxy)pregn-4-en-3-one (CAS 1419705-13-7), a certified reference material (molecular formula C18H36NO5P, MW 377.46 g/mol) for analytical method development and quality control.

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.
