Chemical Structure

(1R,8S,9r,Z)-Ethyl bicyclo[6.1.0]non-4-ene-9-carboxylate CAS 79549-89-6 chemical structure

Description

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.

CATO supplies (1R,8S,9r,Z)-Ethyl bicyclo[6.1.0]non-4-ene-9-carboxylate (CAS 79549-89-6), a certified reference material (molecular formula C12H18O2, MW 194.27 g/mol) for analytical method development and quality control.

The molecular framework of (1R,8S,9r,Z)-Ethyl bicyclo[6.1.0]non-4-ene-9-carboxylate (C12H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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).

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.
