Chemical Structure

Carlina Oxide CAS 502-22-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 182.22 g/mol gives Carlina Oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Carlina Oxide (CAS 502-22-7), molecular formula C13H10O and molecular weight 182.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Carlina Oxide (C13H10O) is characterized by 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).

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.

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.
