Chemical Structure

3-Oxaspiro[5.5]Undecane-9-carbaldehyde CAS 2092688-34-9 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 3-Oxaspiro[5.5]Undecane-9-carbaldehyde (CAS 2092688-34-9), a certified reference material (molecular formula C11H18O2, MW 182.26 g/mol) for analytical method development and quality control.

Structurally, 3-Oxaspiro[5.5]Undecane-9-carbaldehyde (C11H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 182.26 g/mol, it falls into the medium-molecular-weight range. 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.
