Chemical Structure

4H,6H-Indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazinium, 2-(4-chlorophenyl)-5a,10b-dihydro-, (5aR,10bS)- CAS 2766866-71-9 chemical structure

Description

The molecular framework of 4H,6H-Indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazinium, 2-(4-chlorophenyl)-5a,10b-dihydro-, (5aR,10bS)- (C18H15ClN3OBF3F) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies 4H,6H-Indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazinium, 2-(4-chlorophenyl)-5a,10b-dihydro-, (5aR,10bS)- (CAS 2766866-71-9), a certified reference material (molecular formula C18H15ClN3OBF3F, MW 411.59 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.
