Chemical Structure

Ammonium (3R,5R)-7-((1S,2S,6R,8S,8aR)-2,6-dimethyl-8-(((S)-2-methylbutanoyl)oxy)-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)-3,5-dihydroxyheptanoate CAS 77550-67-5 chemical structure

Description

The molecular framework of Ammonium (3R,5R)-7-((1S,2S,6R,8S,8aR)-2,6-dimethyl-8-(((S)-2-methylbutanoyl)oxy)-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)-3,5-dihydroxyheptanoate (C24H37O6H4N) is characterized by a steroid core, 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.

Ammonium (3R,5R)-7-((1S,2S,6R,8S,8aR)-2,6-dimethyl-8-(((S)-2-methylbutanoyl)oxy)-1,2,6,7,8,8a-hexahydronaphthalen-1-yl)-3,5-dihydroxyheptanoate (CAS 77550-67-5) is a high-purity analytical reference standard with the molecular formula C24H37O6H4N and a molecular weight of 439.59 g/mol.

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.
