Chemical Structure
Description
(3S,4S)-14-Ethyl-9-(1-(hexyloxy)ethyl)-4,8,13,18-tetramethyl-20-oxo-3-phorbinepropanoic acid (CAS 149402-51-7) is a high-purity analytical reference standard with the molecular formula C39H48N4O4 and a molecular weight of 636.82 g/mol.
The molecular framework of (3S,4S)-14-Ethyl-9-(1-(hexyloxy)ethyl)-4,8,13,18-tetramethyl-20-oxo-3-phorbinepropanoic acid (C39H48N4O4) 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.
